How do you know if you’re “settling” in a relationship? I need advice. Help

I know this sounds messed up.. but I met him and fell in love and got knocked up really quick and although I love him, I feel like i settled because I’m in late 20s.. he has a ton of baggage and didn’t have his “shit” together., I’ve struggled so much, going through school and getting to where I am. I met him, and I had to completely stop my life, my job, everything, to pick up and move away from a place I love with him so he can start going to school, and I start this whole struggling process all over again because he is now finally starting to get his life together..

Sorry if I sound like an ass, but I think I’ve always thought in the back of my mind that I could do better. Idk. I’m lost. I feel stuck. I do love him, though.. we aren’t perfect, we argue, but he is truly my best friend

I know that this life I have is not ideal and not what I’ve ever wanted for myself. I worked so hard in my life for years to get ahead, and to now have to retract everything.. it’s definitely not what I want, but he is my best friend, and I love him. Idk. Maybe we’re going through a tough time and we will come out of it. Once he finishes school, our life and what I’ve always envisioned myself having in life, will finally come true/happen.

I’m looking for words of wisdom, advice, something.. I’m really lost. I’m struggling.
