How unhealthy is this for my relationship?

I’m 17 and my boyfriend and I are very close. We live together at his mom’s house currently. This is because my mom moved to another state last year and I didn’t want to go for many, many reasons. So my boyfriend’s mom has guardianship currently. Everything has been going really well, but I’m visiting my mom (mostly to see my grandmother) this week and I just miss him so much that it hurts. I’ve been crying every night because I want to be home with him.

The past few months, him and I have been working on this because we do want to have a healthy relationship. He went camping with his brothers for three nights and that was fine. I missed him but it wasn’t bad like I feel right now. I’m not sure if I’m feeling this way just because I miss him, or because I’m exposed to a lot of my traumas here. My boyfriend and stepdad actually got in a physical altercation before because my stepdad hit me. And so now I’m around my stepdad and I’m just terrified because I don’t have the only one who protects me. I don’t know.

He’s just my everything and I don’t want to put us in a position where we have an unhealthy relationship. I would appreciate it if anyone could give me some advice or suggestions as to whether or not this is okay or what we can do to work on this. Thank you.
