Welcome to PC. I've kinda been in this situation. My ex texts me after a few days but he has a gf. It's frustrating. He probably really cares about you but then there's some aspect of me that think that if a guy contacts but doesn't want you, he's just using you as a side piece or wants something from you without having to work hard at a relationship. I don't know much about situation but I'd be kinda careful with situations like this. If you two are friends then that's great. If there's some romantic feelings then I'd be careful because you may get hurt. I'd say don't be so concerned about him and go ahead with your life. Guys who have texted me most of the time either want something like sex out of me or liked me in some kind of way. A friend wouldn't always text you unless they really like you. They would at least give you space. He could be kinda obsessed with you. You know whats best for you. Follow what feels right to you. I hope everything goes well for you.
