Some men , like women will stay because they don’t want to leave their children . It really is that simple .
The fact that you saw that he had written to OW telling her he doesn’t love you is showing you what type of person / husband he is . He’s not committed to you emotionally and has zero respect for you .
He got caught out the first time, made a big show of deleting her ( her number ) from his life . Except ...... he didn’t . He merely gave her another name and carried on typing to her in secret . You know that , he’s admitted that.
Now he tells you that since you got pregnant again he’s stopped typing to her .i imagine he’s thinking you should be happy about that . Why should it take for you to be pregnant again, before he stops typing to her ( if that IS the case , which I doubt) why could he not have stopped and walked away after the first time he got caught and he saw how hurt you were
My belief is that if someone cheats , gets caught , sees the total devastation they have caused , is genuinely sorry and stops that’s not great , but maybe something some people can work with . If someone cheats , gets caught , sees that same devastation, and does it again , he’s showing you he just doesn’t care whatsoever, not at all , for you , your hurt , nothing .
He’s keeping her number for a reason , maybe he has ,for the time being ,stopped typing to her , but the chances are , one day in the not too distant future he’s going to be bored , tired , frustrated from lack of sleep , life returning to normal , everyday life stresses ( any or all of these ) then he’s going to get back in touch . When, as other pp has said , he wants a bit of an escape from reality , where in his dreams he’s footloose and fancy free ..Her number is there for a reason , if she was nothing to him he would have got rid by now . Her number is there because he wants it there .
You just need to ask him ,tell him the stress is having a negative impact on you , and therefore can’t possibly be good for the baby . Use a bit of guilt . But it’s true as well , this emotional upheaval can’t be good for your child .
He’s shown you he’s untrustworthy, you just have to decide weather you are happy to spend the rest of your life with someone who doesn’t love or respect you enough to be completely honest with you .
Judging by the type of person he sounds , if he does get rid of this OW , she will be replaced by someone else . It appears that lying , cheating and hurting women is just a part of who he is .
Sorry . It may sound harsh , but you will very unlikely find an inner peace and security with this man , you and your children don’t deserve a life where deception is the main ingredient . It makes for a lonely and miserable life
