So 5 weeks ago my husband left myself (7 months pregnant ) and my 3 year old daughter for an 18 year old he met on a stag do. Completely out the blue, no warning and it was only because I caught him texting her, not because he came clean. Now aside from feeling like I'm living an episode of Jeremy Kyle, I have had him mention quite a few times now how one day his girlfriend will be part of both my kids lives. My question is how long do normal people wait before introducing new partners to their children and what rights do I have about who is around my daughters? Even after everything he has done, I have still made every effort for him to continue a relationship with our now very fragile 3 year old but I feel like this is a ridiculous conversation to every broach with me right now. It's been 5 weeks and he has only known her for 2 months. And the girl has definitely been showing her maturity level with the public displays of affection she posts all over the internet, bragging about their relationship which he completely indulges in with them both going out their way to ensure I see everything. They are beyond disrespectful and have no remorse over their actions. I don't really want that kind of person round my children, it's bad enough their own father has that sort of behaviour.
He took it upon himself to show our daughter pictures of this new girlfriend at the weekend, told her who she was, her name etc and my little girl ended up heartbroken and so confused. He apologised and said he had made a terrible mistake in doing so after how she reacted but I obviously don't trust that his intentions are to prioritise what's best for our children.
I've asked him to keep her separate from our daughters but I don't know what else I can do. Any advice would be great. Thanks
