So me and my partner were going through a really bad patch - he never wanted to be at home, wanted to be out with friends all the time and left me at home with the children (including a new baby) we then went out for a day with friends - he made every excuse for me not to come and when I turned up late there was another girl sitting with him - we split up a few days later.
He then began messaging this girl and god know what - I know he really liked her but in the end she finished things with him. He’s now come back with his tail between his legs and wants to try again - I can’t get over the fact I’m second best - but the children really want there daddy home, he said he can change - what do I do?
