Cheating

The fact that he’s been talking to her when you’ve had an argument means to me that he’s been seeking that comfort from her, it’s completely and utterly wrong! The fact that you have a 9 month old too just makes him look even worse! I wouldn’t put up with it! You deserve so much more than that!! You don’t deserve someone who’s not going to be by your side when you have an argument! Every couple argues like myself and my partner but if I was in your shoes, I wouldn’t be standing for it. I have a 10 month old with him but that would be the hardest thing is to say it’s done because of what he’s done running to that girl. But with him muting notifications is just even worse. He’s not even denied it at all when you’ve come across it. If you need a chat my inbox is always open girl. It’s not easy at all, but you need to do what’s best for you and your baby!! I wouldn’t stand for that at all!xx

What a cliche, it's cheating even if he's not gotten to the sex part. He's been deceitful and I'm so sorry. It's very easy to say he'll do anything but he chose to exchange numbers, he chose to use a fake name, he chose to mute her, why all the dishonesty.
And if he'd spent the time while you are your most vulnerable giving that attention to you and your daughter would there havie even been fights for him to go run off with her and have this emotional affair?

You sound in shock lovely, key yourself feel your feelings but unless he's honest, genuinely remorseful how can you rebuild trust? Don't accept this weak gaslighting bs, ask him to show you not tell you. Gosh, had he even apologized?

You deserve so much better x

You know what to do but your scared
