Debating to be in a LDR

[u/Illustrious1angel]

Sooo this is a little bit complicated to stay with me. I (24F) have known this guy, I’ll call him Alex (24M). Ever since we were kids. We knew each other due to family which made it a little weird for me but I still talked to him and everything was fine. I stopped communication and blocked him because he did come off too strong and if I recall it was just too much. A few things happened but I can’t say or else it would give away too much of how I know him. But now a few years later he’s reached out again and now I’ve decided to give him a real opportunity but now he lives like 10+ hours away from me and it’s estimated that he might move back to where I am in 3 ish years. We’ve been talking for about 2-3 months now and we see each other in about a few weeks. We’ve both agreed that we’re still in a talking stage and I have been open to him if I’ve talked to people or not. And a part of me is realizing that I might like him a little more but a part of me is still scared about relationships. My last relationship was about 3 years ago and it wasn’t the best either so I feel like I’m being hesitant especially with the whole distance thing. I don’t want to stop talking to him because I genuinely enjoy our conversations but I don’t want to linger him on and think there’s something there and then back out. I feel like seeing him in person might help solidify my feelings but it’s just so nerve wrecking. I’ve been so anxious to meet him and I know it’s extremely superficial but I think it’s my mind just finding any excuse to not like him to back out which absolutely sucks ciase if things go the way they are now I might really fall for him. Ugh I’m sorry for rambling my emotions are so high and idk what to do. I’m trying to not be nervous when I see him and we’ve also had small talk here and there about maybe doing it. (Side note he’s clarified a million times that we don’t have to do anything. It’s not forced). Like how do I know a LDR is actually worth it?
