I’m confused (short story)

I’ve have liked this boy for a long time. I finally told him. He said he felt the same but things are complicated for him ( he just got out of a long relationship) . Me n the boy start getting very close talk on the phone everyday for hours. Check up on each other. Just spend a lot of time together. Eventually we had sex. And it only made us closer. He always tells me he wants to get married and be in a happy relationship but just not right not. I want the same thing but it’s complicated. (We are in our mid-ish 20s btw , he is 4 years older than me) idk if I should continues and wait to see what happens or should need to move on for good. (He is talking and messing with other girls and I don’t want to talk to anyone else)
