Help!!

Hi! So my current boyfriend and I have officially been together for about 3 months, but we’ve been hooking up/developing feelings for about 5/6. Last night I found out that he got a girl pregnant before he met me. He found out around the time we got together and told me last night because while she was kinda using him as a sperm donor, cause he’s very attractive, now she wants him to be involved. I’ve dated people with kids before but this is a bit different for me. I’ve had 3 miscarriages from an abusive relationship and now when people near me go through their pregnancies I feel the hurt from my pregnancies.

How can I support him through this but also take care of myself? I’m not jealous so much as it just hurts because I’m going to see some lady get to have her baby, which is already hard for me and it’s also from the man I want to have kids with one day, which hurts too. Please help?😬😬😬

Please do not tell me to leave or rag on me. I’m just looking for maybe people who have been through a similar situation and can tell me how they got through it.

Thank you!!
