Trigger warning for discussion of pregnancy options/abortion

I have diminished ovarian reserve and didn’t think I could get pregnant. Recently came out of a 10 year relationship with my 7 year old son’s dad. He’s very unstable. Been seeing my current partner for just over a year and he’s amazing. We have a beautiful relationship with great communication, passion and respect for each other. He also has unresolved trauma that he is in therapy for. He struggles with emotional regulation/panic attacks. It affects his ability to go to work sometimes and he is prone to impulsive decisions. In our relationship he has been 100% committed and supportive. He really wants this baby. He has no children but treats my son as his own. I have a secure career and am moderately high earning.

This is possibly my last chance to have a second. But it’s been so long, I had given up hope. I’m terrified to do this again after my son is finally more independent. I feel our relationship is new, and we have so much I wanted to grow and explore with my new partner. Jumping into parenthood this early is terrifying. Putting my body through this is terrifying. Giving up my freedom and committing to another man after a shitty 10 year relationship is terrifying. How do I make a decision like this??
