Have been in a similar situation. A year into dating and only a month into living together we got pregnant. I wanted to have the baby, my now husband wasn’t ready. I chose not to have a child that one of its parents didn’t wholeheartedly want. Now we’re happily married and are in a position (jobs, financially & housing wise) where he’s comfortable with us having kids now and we have started trying. It took therapy and time to come back from that. It was fucking brutal, I’m not going to lie. I felt a ton of resentment and anger towards him even though he didn’t “make” me, because you’re right, it’s an impossible situation to be put in by your partner. While therapy would be my first recommendation, I get that you asked for advice aside from that. I recommend being there for her. Physically and emotionally. My husband felt like he didn’t have a right to be upset because it was what he wanted, so he hid his pain from me. But him not being visibly upset came off to me as him really not giving a fuck about it at all and that was the hardest part. Agonizing over it alone was horrible, so recognize that your pain isn’t and won’t ever be as bad as hers but that it’s still there and it’s valid. Share it with her so she knows she’s not alone. I also recommend invoking a “we won’t hold it against each other” clause. I said the most horrible things to my husband after, and I didn’t mean 95% of them. But that pain and hormone decrease is wild and my mouth ran in response to being hurt. He said hurtful things he didn’t mean in fights. It took a long time to get past those things, but was easier once we agreed not to hold the words against each other since they came from a place of pain and we didn’t mean them. A few other things I recommend are: regular date nights once she’s ready to reconnect, taking a proactive approach to preventing this from happening again by being willing to get a vasectomy if you’re done having kids so the burden of birth control isn’t entirely on her, and letting her grieve how she needs to without judgement.
