OH and I have been living apart for two weeks but not finally 'over' last night he stayed over and this morning I checked his phone (please don't judge me for this). I found texts to and from a girl he'd met in a taxi queue and pictures of a girl in his photos dated 4 days later not sure if same girl.
We've been arguing a lot. He constantly puts his daughter from a previous relationship before myself and our new baby even planning a holiday for them without telling me til it was booked. He says spiteful cruel things too like calling me a slag/bitch/leach etc.
It would seem that as far as he's concerned you are 'finally over' and he regards himself as footloose and fancy free, but it would appear that he hasn't scored yet otherwise it's unlikely he would have stayed over with you last night.
However, as verbally abusive twunts like him find it difficult to keep up their 'nice guy' acts it's possible that when he does manage to get his leg over with fool an ow he'll keep you on as his verbal punchbag until she becomes as accepting of his misogyny as you are and you're best advised to get yourself tested for stis at a GUM clinic if you intend to engage in any further sexual activity with him.
The only good thing that can be said for him is his devotion to his dd and it's to be hoped he'll also prioritise the dc he has with you over his future relationships.
I think he just says whatever he thinks the relevant X wants to hear. "I'll put your child first" and then to the other X "I'll put our child first".
I've lost respect for him. Two babymamas and he's already chatting up girls in taxi queues whilst using your house as a port of call. He has brought two children in to the World and it sounds like he's all big words but quick enough to move on.
