Thanks@all for ur advice and encouragement.
@chaircover,I'll have a heart-to-heart talk with him as u suggested. I'm really curious to know why he did that.
@Meddler,thanks for ur concern. I'm seriously on the watch from now on. I don't want to die young.
@ronkebp,I never believed it could happen to me. Hope he's truly remorseful as I want this marriage to work.
@likeme,I'll take ur advice.
But MYY GODDD!!! Ain't I enjoying this early homecoming? I've decided to give him sex anytime he wants,whether I'm tired or not. But he has a high sex drive,God help me.

So,last Sunday night,I picked up his phone and scrolled thru the messages. I kept on seeing a number with no name. I opened one of messages and a love message greeted me. Same with others. I saw a message by 11pm on that Friday,reminding him he said he was coming,and that he should bring some bestseller movies along. My husband came in while I was  reading the messages,and I showed him one of the sms. He couldn't talk. I went to the sent messages,and I saw the shocker. He was also sending love messages to her!!! We had some family members around,so we couldn't talk then.
    He later tried to explain that the girl was a schoolmate who recently had a bad breakup,and was now after him. Said he sent those messages out of pity. Said he was not with her that night but in another friend's place. I refused to believe that. He later said he was with her all those nights,that he was drunk,but that he never slept with her. That he was trying to be nice to her. I insisted he must tell me the truth abt if he slept with her or not,otherwise,that I wouldn't forgive him. He kept on denying it. Annoyed me further by calling his mother to talk to me,who told me to take it in my stride and endure. Later threatened to commit suicide if I didn't forgive him. He had to miss work on Monday,trying to convince me. Guess who the 1st caller that morning was,the babe.
   I got him to call her in my presence and tell her it is over. I forgave him and for the 1st time in a long while,he reached home by 6pm yesterday.
However,I'm afraid he's just trying to pacify me and may go back to her. He is still denying sleeping with her. I also don't like the fact that I have to be suspicious of him all the time. I wish all this didn't happen. I decided to post this here because I can't talk to anyone abt it,But I have to let it out.
Your comments will be appreciated.

His frequency of late-coming increased. Then last Friday,he called around some minutes to 11pm ,saying he was on his way home. I waited for him till 12mn and then went to bed. By 1am,I called him,and he told me his car developed a fault,that he was with some mechanics and would come home as soon as he was thru. Maybe,it was the echo in the background which showed he was in an enclosed space and not in the open as he wanted me to believe,or the sound of a dog barking in the background,or his sleepy voice,I don't know,but I suddenly realized he was lying. I told him I thought he was lying,which he denied. I switched off the line. He came back some minutes to 2am,pretended all was well,and hit the bed snoring.
    The ff morning,I told him I thought he was having an affair,and that I've realized I'm on my own in this marriage. I told him To build his house alone,that I'd no longer support him,and that I'll not sleep with him again b4 he gives me HIV(I was bluffing). I was on my way to work and he was driving. He started begging,was crying,and almost caused an accident due to loss of concentration. He still denied having an affair,but from te way he cried,I knew something was up. He later bought me a sorry card,and some gifts. I told him I'd forgiven him,but deep down I knew he wasn't telling me everything.

I'm not a new nairalander ,but I created a new ID to conceal my identity,just in case.
I've been married for two and a half years and we have a baby. I always thought my husband was madly in love with me,as all his friends always told me my husband talks abt nothing else but me. He tells me how much he loves me,buys me gifts,helps out in chores and even takes care of our baby more than I do. I couldn't ask for a better man.
However,he has a habit of coming back late from work. He's a banker,and always claims that one thing or the other kept him. His can stay as late as 11pm. I always complained abt it cos some of his colleagues who are our neighbours usually come back btw 7-8pm. I attributed it to overzealousness until recently.
Abt 3wks ago,he left home around 5pm(it was a weekend),saying he had to see some friends. Around 11pm,I got worried cos quite unlike him,he didn't call. I tried calling,but his phone was switched off. I waited till 11:30pm,then called the friend he said he was going to see. To my shock,he said he hadn't seen him that day. I had to call his colleague who is a neighbour who had to call a few other people to get the number of the other friend he was going to see. When I called this friend, He also said he hadn't seen him that day. I was afraid something had happened to him. It didn't even cross my mind that he could be at a woman's place. He later came in around 12mn,told me a cock and bull story of how he was with an old male friend of his,and how network was so bad he couldn't reach me. Was annoyed with me for calling his colleagues,saying they're now suspicious of him.
