Crossroads

I'm so completely lost. I love Ian, I always have and I always will. Every time we're together it's perfect. In my head I know he's just in it for the sex, but I always block it out. I mean he was with me for years before we did anything past kissing. So that counts for something right?
Then there's David, and literally he's the sweetest guy in the whole world. But I don't know if he's that into me either. Like after we got back from Corpus he hasn't really wanted to hang out with me. At least, I don't think so. But when we were there he was really really cool and didn't mind holding my hand in public and kissing me in front of his friends. Which was really good since Ian mostly kept me a secret.
I don't know how to feel. Ian's coming back in the summer, but maybe then I'll want to hang out with David, you know? I wish I could just let things play out and see how it goes but my worst fear is that I'll be forced to choose...soon. And I don't know who I'd choose. There's something to be said about a guy who's kept in touch with me for four years now. But there's also something to be said about having instant fireworks with a guy and wanting to know him.
That's how I feel about David. Like there's so much to find out about him. Like we have an adventure to go on. But with Ian I still feel like I love him. And I honestly don't think I'm ready to let go.

So what do I do?

Should I just try and forget about Ian and see what happens?
Should I just stop with David before I get too attached?

I really do love Ian.
But I think David would be good for me.

I don't know.
