Hi guys, thanks for the advice/responses once again.
Well, the day after he asked me if we could go to the pub with her, I was still feeling a bit niggled by it to say the least, and couldn't stop feeling uncomfortable when he was chatting online with her, even though he wasn't hiding his behaviour. I said I wouldn't check on him again but I was alone all day with my thoughts (I know that's a crap excuse) and eventually I just thought "oh for gods SAKE just go and look and stop stressing"
So I checked his email and saw an email conversation with her that was like "I'm sorry about last night, I feel like an idiot for saying what I did, hope I didn't make you uncomfortable?" from him to her. OMG too intriguing to leave alone! I went and read his chatlogs again and I'm so glad I did.
It was a long conversation and I had to read quickly (he can check his computer from work and would be able to see what I was doing) so I can only give you the gist, but basically at the beginning of the conversation she seemed to be trying to coax him into admitting past or even current feelings for her.
He played dumb for a while but eventually said "ok look, 12 years ago I had a crush on you, but it was a long time ago. My feelings towards you now are a moot point because I have fedup1981 and our baby, and I'd never hurt her" (yay!)
She also mentioned a message I'd left him on the social networking site where they met (not subtle: a kiss mark with a message of "come to bed, you") and asked if he thought it was a message to her that he was mine. He said it probably was, and she said "oh I feel bad for making her feel the need to do that, maybe I should leave you alone"
Then the rest of the conversation was really awkward and stilted, she was obviously quite pissed off and trying to conceal it/save face by saying "You're obviously busy/talking to someone else/fedup1981 needs you, so I'll let you go" etc
I'm so chuffed he said what he did, he even mentioned how emotional the birth of our baby was and stuff which made me laugh as it must have been a big turnoff for her since she's obviously using him for an ego boost!
So I felt 100% happy yesterday, and happy to stop checking up on him. But last night he spent 3 hours talking to her, 2 of which were after I went to bed and now I'm wavering... I don't know how to stop checking up on him, it's not good. I haven't checked today though. I will try to keep busy so I'm not tempted.
Madamez, I can understand how you got the impression that you did that dp is constantly questioned and suspected but I can assure you that this has never come up before, and I have literally only said to him "When you were chatting to that girl the other night you had a silly flirty smile on your face and it made me really worried, should I be?"
I want him to have friends but I don't think you can have a totally platonic relationship with someone you were crazy about in the past. Put it this way: he doesn't send little messages to his male friends when they aren't online saying "I just had a little sulk cos I missed you online, maybe we can talk tomorrow night?"
In fact, he always told me he didn't much like chatting online, he certainly doesn't talk to his male friends online for more than 20 minutes at a time, and he can go for weeks without talking to them.
I honestly am not a jealous person, I once had an open relationship with another boyfriend, but now the baby is here it's an absolutely different kettle of fish. We need 100% commitment and monogomy, because that's what I'm giving him.
Tamz77, I will think about telling him the whole story, but if I'd have told him at the time I never would have read the conversation above where he pretty told her he wasn't going to do anything to hurt me, so for now I'm staying quiet (the less I bring it up the stronger and less jealous I appear)
Regarding the supposed meet-up, I still don't know what to do. On one hand I'll feel inferior and defensive, but on the other hand I'm still smarting that he told her I might not go because I'm not very sociable. I feel a bit like going just to show him I'm not as predictable as he thinks. But it will be torture for me and he will have got his own way as usual.
Oh, and finally (sorry this is SO long) if we do go, I'll be tempted to check their chatlogs afterwards and that really could spell trouble.
