Hi Maggie. Just in from work. I hope you won't mind if I respond to points on both your threads here.
The mother issues might be a bit of red herring, as it sounds as though he's always had good relationships with women.
From what you've told us, he is only 28, meaning that he got together with you when he was just 22. It takes some men an eternity to grow up and this could be as simple as he's not actually ready to commit to fidelity at this age. The difficulty for you is that at 33, your clock might be ticking and depending on what you tell us, you might feel that time is not on your side to make a decision about having children. So, if having children is important to you, do you cut your losses now and find someone else - or do you stay with this man and risk having children with him? Having children was for me, a far bigger commitment than marrying. I wouldn't have entertained the prospect if I wasn't sure at the time that my H would stick around and be faithful.
You might be able to clear up a nagging suspicion I have about something. You say you were in E mail contact with OW yesterday when she reassured you. How do you know for sure she didn't phone your DP after your first E mail? Given the fact that she'd supposedly learned only that day that their secret was out, a text after an 8 month gap asking him "how his weekend was" (when she knew from you it had been bloody awful) sounds bizarre. And telling his best mate? Very strange.
It's interesting that when the texts happened, you spoke more to your counsellor than you spoke to him, by the sounds of things. You raised a point on your other thread querying whether because you didn't deal with the issue then and the lessons weren't learned - could they be learned now? It's possible - there are so many threads about these texting relationships and if there's one thing I've learned, it's that these are never harmless and removing the third party from the equation never solves the problem.
It sounds as though every time he has doubts that the relationship is going to work, he dallies with someone else. This adds to my impression that he is very young for his age and therefore not great husband and father material. As you imagine, parenthood forces us all to grow up pretty sharpish and it's all about putting children's needs before our own. Could he really do that? You say you cannot give him the attention now that his mother gave him. Imagine how much less you'd be able to give him when all your nurturing needs are subsumed by a child?
It seems obvious to me that the reason he didn't tell you about the infidelity when you were suspicious all those months ago was so that he could carry on.
Telling you now therefore carries less weight, but I agree with you that it's good he told you. Whether his reasons for that are as altruistic as he says, are open to debate, but the effect is the important thing. He has given you a choice. I'd always prefer that, than to make choices in blissful ignorance.
It might help you to write down what you're most angry about, concerned about etc. If you're not good at verbalising things, this often helps.
