Relationships 😔

I'm currently feeling like I would love a relationship, mainly to have someone I can talk to, be intimate with and have fun; basically a best friend but without the fwb complication. I'm 18 but I've never had that before and I don't have any friends (out of choice following a bad experience). I'm not purposely looking for a relationship because I know stuff happens when you least expect it but is it normal just to want something like that? I'm chatting to someone on an app but tbh even though I feel a connection, I don't think he's that interested. Should I just completely forget apps and let fate happen as it were?
