SO cheating

I wrote the other day about my BFP and how my SO decided it wasn't the right time. Even though we were actively trying..

So I leave it a few days and re address it. He literally breaks down and says he's been seeing someone for the last year and she's pregnant.. She's due in 3 weeks.

i didnt cry i didn't shout

I asked him to leave and he didn't argue as the child was there. I'm better than all of this, if she wants him feckin take him. I'm not a weak person by any means but when he left and the child went to bed.. I cried. I literally don't know what to do now 😭😭😭
