Who to walk me down the aisle?

So to start I'll explain my past. I grew up with a very abusive father. It wasn't until I was about q4 years old that my mom finally got the courage to leave. At this point there was my brother (16), me (14) my sister (8) and my other sister (6). Unfortunately my mom had to work 2 jobs and was exhausted all the time. Somehow things ended up that I became the "mom" of the household. At 14 I took care of the finances, making dinner every day, helping my sisters with homework, etc. I was not allowed to go to my friends homes because the 2 weekends a month my mom was off was her down time. So I always had to be home. I was thankful for my mom working so hard, but resentful for the life I lived. I had a strange relationship with my mom. Fast forward several years and when I was 25 I became a mother. My child's biological father wanted nothing to do with the baby so I knew from the beginning I was on my own. My mom hardly spoke to me during my pregnancy. She always had negative things to say. When I packed my hospital to-go bag one week before the due date my mother riduliculed me that I was doing things to early and needed to "chill out." I was just trying to be excited. Many years of struggles with my mom continued. Meanwhile I met a guy and his family. I truly felt loved by them. This guys Step-dad, Paul, starting introducing me as his daughter. He co-signed on several things for me to help me build credit. When I bought my house I was short on all the unexpected money I would need just before signing and he handed it over without hesitation. The guy and I had a brutal breakup, but his family and I are still close. Paul still calls me his daughter, and my daughter he says is his grand daughter. Trouble is, after I get married, we will be moving away from Paul. And most of my relationships don't last once I don't see them regularly. My mom and I have worked on our relationship and we are in a much better place now. I remind her when she's being a "negative nancy" and she tries to correct her words. My mom eagerly wants to walk me down the aisle. Paul hasn't said a word. I would be happy with both of them walking me down. But now there is so more complications. My mom is now engaged to a wonderful man. They have been together for 5 years, though I hardly see him. When we bought out house he kindly gave up his old appliances and delivered them. My mom worries he will be offended. And my mom admitted she's a bit offended I'd ask Paul too, because she raised me since birth whereas Paul has only been around for 9 years. Also, for Paul, he has one biological daughter and due to a dispute between him and her many years ago, he never got to walk her down the aisle. So I'd like to show my appreciation to him and in a way give him this moment or memory.

Anyway... idk what to do... advice?
