My Boyfriend Had A Female 'visitor' For One Week

I am in a dilemma: My boyfriend recently had a female visitor from delta and she actually stayed over at his place for a whole week. He didnt inform me about the visit and i only found out when they both came to visit me.The most annoying thing is that he comes in the company of this girl whenever he is coming over to my place and they go out together whenever they leave my place. All through her stay, he never allowed me to visit him but would rather come around to see me.In all sincerity, the girl told me on the first visit that she has heard so many nice things about me from the guy which she didnt specify. Anyway i discovered the day the girl left his place that he has been the one responsible for her staying for a week because each time the girl wanted to leave he keeps begging her to stay{all these from his inbox and outbox}.Would u believe that i asked him for money and he told me he didnt have, that infact the girl was the one responsible for all the spending that took place all through her visit. Do you think i should just bow out of this relationship because really i started taking my mind away from him ever since.

 Ipso facto, u got no case, me tinks u jst greedy and wont share!!!!!!
