<human>: Can you summarize the given text in a few sentences?

So I'm 19f, he's 19m. We've been together for 6 months. There were some complications during the start of the relationship. I almost broke up with him but we worked it out and are really solid now as a result. 

After we resolved our issues, we really started to grow close and some serious feelings developed but he had to go out of the country for a month and a half. This has been kind of difficult for us because of the timing, but we've actually grown really close during this period--we skype/text/facebook chat everyday and have repeatedly expressed our strong feelings for each other. 

We have discussed this before, but saying "I love you" is kind of a big deal for both of us, we think it's a big step. He casually said it to me the other day but I haven't said it myself. Part of me wants to wait until he comes back home(2 more weeks!) but another part of me can't contain it. I almost said it on Skype last night but got too scared. That's another issue.

I care about this guy so much and have no doubt in my mind that I love him, but I'm afraid of expressing it. It's not like I'm afraid of rejection since I know he feels the same way, I guess I'm more afraid of the fact that I feel so strongly about him. That vulnerability really scares me and I'm not sure if I understand it, or how i can get past it. This is my second serious relationship. First one was in high school, but it was a really unhealthy relationship. This one feels right. Anybody have any insight?
<bot>: I love my SO but I'm afraid of those feelings and afraid to express it. Not sure if its because he's out of the country or because I'm just afraid in general
