FWB (Casual Relationship takes a turn)

Several months ago I started casually dating. I had never tried it before so I was nervous. Thankfully I only had to talk to a few people before I met my current friend with benefits. We have been fwb for a while and I still enjoying hanging out with them. Our communication when talking about the terms of the relationship has gone well. We established early on we could go on dates with other people. But they are the only person I’ve been consistently seeing. Recently, I’ve noticed their behavior has changed. We are about to talk about it soon because last night they asked if I want to go out. Usually they say hang out so I’m assuming they mean a relationship. But I have high expectations for my next relationship. I spent almost four years in a highly committed relationship. Just to see it end because I wasn’t enough for them, since they wanted to date other people. So for my next relationship I want the person to be as committed as I am. I don’t want to waste another couple years, if I’m going to date someone it will be with the intention of marriage. I also am struggling on figuring out the next steps in my life. I was originally supposed to move to a different state with my friends and one of them happens to be my last ex. We have a very intertwined friend group. But I’m getting almost no communication from them now almost two months prior to the move. I’m very stuck on which direction to go. I figured I can’t be in a relationship if I’m in an in between spot because that doesn’t seem fair. And it doesn’t seem fair to keep being fwb if the other person caught feelings when I’m not sure I guess. I think I would only know how I feel if I knew where I was going. I really don’t know what to do….
