Tough love

I'm IN LOVE with someone and she says she loves me too, but we're not together. She's never been in a real long distance relationship (unlike me) so it wasn't working for her because it was something new.. We don't really talk that much but when we do things feel great.. I guess she's talking to someone now but I can't seem to not think about her. Should I give up on there ever being an 'US' or wait for her? I've tried not talking to her, deleting her #, deleting her on social media but we just ended up adding each other back.. If she didn't love me she wouldn't keep contact and tell me she loves and misses me every time we speak right? I really don't want a relationship with anyone else if I can't be with her 😩😔
