Here's some background info so everything makes more sense:
Around March/April or maybe a bit before, I noticed my boyfriend had been acting kind of distant (not himself). I know that at times I can be smothering, and we live together in a very small space in a city that he doesn't like, where he has few friends.. so I thought perhaps he was down about that. I never confronted him, I just let him be.
Eventually, around May, he was back to his usual self and this were really really good between us. Like better than ever. He suddenly started putting in a lot of effort and we were both really happy.
At the end of May, he was away for a weekend. I don't know why I did it, but I ended up going on his laptop and viewing some of his skype conversations. There was one in particular that was inappropriate - he was talking to a girl he knew from his hometown (on the other side of the country) and saying things like " you're so pretty", "I wish I could snuggle you to sleep". I read these and panicked because I didn't know how to tell him I snooped and saw this. I told him anyway and he apologized and we talked about it and I was willing to forgive him. Also, the conversation I read was from about a month before I actually read it, meaning they had stopped talking (at least on skype), which would seem to be around the same time he started acting more like himself, so it kind of makes sense. He said he was having a rough time and he messed up and he told me I don't have to worry anymore. He deleted her number from his phone and I told him I don't want him talking to her anymore and he said he wouldn't.
Anyway, I have found no contact between them since (it's been 2 months). I've seen his phone and there was no trace of her there. And I have access to her FB page, though we are not friends. She doesn't use the privacy setting. And I can see that he doesn't post on her wall or like he statuses or comment on her pictures or anything like that.
I asked him recently (he was going to be in his hometown, within close access to her town as well and was feeling a bit down) if he was going to be around his this weekend and he said no, that I didn't have to worry, that he didn't talk to her anymore, and that she knows he's back in love with me. That was a good explanation for me.
Except now, this trivial little thing..
my boyfriends FB status was something like "wishes he could be in *** with his cousin DC"
his cousin DC is friends with this girl he had flirted with. This girl liked his status on FB and it makes me feel insecure.
It's not like he had anything to do with her liking his status. And he recently said to me it was his mess up, not hers or mine.
So it's not really his fault she liked it but it makes me feel like he's maybe lying
although things have been good between us in terms of him not being distant and his being affectionate and attentive so nothing weird is going on there.
Should I let it go?
