Going through a breakup - pregnant with somebody else

29, F here - here is my situation. I don’t want any judgment please but any advice welcome.

Me and my ex split up about 6 months ago. We still have a house together although he lives at his mums. We split due to his drinking causing arguments between us. He is a good guy and I love him but we wasn’t benefitting eachother during that moment.

Since then, I have become pregnant. (8 weeks) He is not the father. It was a one night stand. I was being safe but this happened somehow and now I have to deal with it. The father wants to be in the child’s life and has even suggested we date and see how things go. I am from the UK where abortion is illegal up to 24 weeks however I am soon to be 30 and for me it just doesn’t feel right to end the pregnancy for a selfish reason.

This week, my ex has text me to say he is really missing me and wants to try again. He is struggling mentally and this makes me sad. I felt okay in the hope he was moving on (as much as it hurts) but hearing this has completely knocked me. Since then, I’ve been crying over my ex and missing him. It’s a painful realisation that we can’t be together ever again now I have done this.

We still have the house to sort which is painful enough whilst navigating the complexities of pregnancy.

I feel broken and don’t know how to get over my ex and feel happy again and enjoy my pregnancy. I feel like an awful human being right now.

Any advice welcome 🙏
