Can I trust my partner?

[Chelle]

Hi

I'm almost 9 months pregnant and have been with my partner for 2.5 years now, we have however known each other since school. Last night I had the worst dream that he'd left me his ex girlfriend, I thought it was probably my hormones playing tricks on me however I'm also aware he used to message her on Facebook, now what I did was not clever but I guess you could call it a hunch so I looked at his messages, it turns out he and his ex had a conversation on there in july last year, approx 2 weeks before we found out I was pregnant, the conversation wasn't what I would have expected, it included how she was on holiday sunbathing to which my 'boyfriend' responded how horny the warm weather makes him, he asked for a photo and she sent him one of her breasts (she was wearing a bikini)

The whole conversation has sickened me to my core, it also goes on how she's asked him to come over to see her to which he replies he can't because he knows what would happen and he's not that kind of bloke, she also stated she's not that kind of girl..... and yet they obviously see no harm in the flirting and telling each other how horny they are!!!

He mentions how he dosen't want to delete her as he enjoys her as a Facebook chum and he likes to see what she's up to even though he won't like any of her things incase 'his Mrs' sees it.

Since this time there is no evidence of any more talk between them, obviously he found out he was going to be a Daddy so I like to think that this is why but now I just feel hollow and honestly don't know what to think anymore as I realise my pregnancy hormones may be taking a hold of this situation.

He's always putting photos of us up on his wall and his profile pic is us, he's put our baby scan pics on there too, I've noticed that his ex tends to like them but theres never any banter between them...... Could somebody please give me some opinions on this matter as I'm so confused all of a sudden. I thought we were soulmates, now I just don't know anymore.

Thank you
