Does anybody feel since finding out they are pregnant that they have gained a miracle but lost their partner?

I’m 13+2 and I have never felt so lonely my boyfriend chooses to go out every weekend and I’m lying here now at 6.40am English time and he still isn’t in from being out since 12am yesterday? If I call him out on his bullshit “ im the irrational one” I feel like the only option I have is too tell him to go but it’s such a hard decision.

I have two children aged 9/10 from

A previous relationship and I never planned on having anymore, but my partner doesn’t have any so agreed to giving him this child and now I feel like I’m going to be a single mother again 😔
