I think the support on here is helping a lot, I do keep checking for replies. I've got lots to do around the house, So I've got lots to keep me busy. Also last night, I was thinking, about him moving in weekends too, and looking back I wasn't 100% about it. I think I just had it in my head that I needed him there because I was having the baby soon, but I wasn't as ok with it myself as I thought I was. I know that sounds odd because I kept pushing and pushing him to do it, but there was always doubt in my mind about how it would work. I don't understand it myself but just getting it off my chest.
This is a brilliant and very, very healthy thing to have recognised and acknowledged. It's a red flag.
Red flags are often explained as 'dodgy behaviours' by partners, but they are, in fact, your own emotional responses. So, for example, if you start dating someone, and they want to speak on the phone every day, that might make you feel like they think you're great and your feelings towards them are reciprocated, or it can make you feel watched and supervised and very uncomfortable. There's nothing wrong with the behaviour, or the partner, but it's a red flag for the relationship if your emotional response is the latter.
There's something going on for you regarding invalidating your own emotions. You didn't feel 100% about him moving in (and possibly other things, if you think really hard?) but you ignored that feeling and carried on. Usually this happens when someone has regularly had their feelings brushed aside whilst they were growing up. Could that be the case for you? If so, that takes all the responsibility for why you allowed this to happen off you, but, gloriously, gives you all the power to make all the right decisions in the future.
I had a similar emotional epiphany, and really can only thank the person who left me. It was the best and most valuable lesson I've ever learned. Life changing. I hope the same happens for you. It will be the most wonderful lesson to teach your children, too, and really, so simple: Listen to your emotions.
