My boyfriend and I have been together for 2.5 years, we've had a good relationship (few up's and down's, but who's doesn't). Anyway, over the last few months things have been different between us, I feel like he's pulling away. I have noticed that when a certain female 'friend' on Facebook posts any pictures of herself he sits there and stares at them, even when I am sitting next to him! She is a lot slimmer and more attractive than me, but I still feel it's wrong of him to do this, don't you agree? I spoke to him about it last night and after a good 10 minutes of denying it, he finally confessed that he slept with her twice around 5 years ago. Now I'm not bothered by any of his other exes, but this girl really bothers me. Possibly because he drools over her photo's, and when we've driven passed her in the car she stares at him too. This girl also has a child, who is approaching 4 years old. This child may be his, he's always told me he wants no children, so for him not to have contact makes sense. I asked him and he said no, but lets not forget he denied sleeping with the mother at first.
This is killing me, I am so anxious and restless. I can't sleep or eat. I feel physically sick at the thought that he has feelings for another girl, and she may be the mother of his child.
What do I do? Can someone please give me some advice?
