How do u know when your boy friend is no longer interested in u?

if he does not call you
like he used tooo
when he starts this disrespecting you
he does not buy a gift for any holiday or birthday or even valentines day
when sleep beside him and he does not touch you every time you see him
you guys argue constantly every day
he is giving you  clues that he wants out of the relationships

when he does not talk to you for days. even though he see you.
when he gives, but you dont receive.

when he does not talk to you for days. even though he see you.
when he gives, but you dont receive.

all that the other 2 posters have said.
perhaps he needs lithium

If he is distracted whenever you are together, leaving u to do all the talking.

If he gives excuses for not showing up for your dates or shows up late for dates.

If he is not eager to meet up with you or seee you.

He goes for days without calling u or chatting with u on-line Where both of u are not in the same town.

when his joy stick will not harden up after u have dropped your undies
