Okay, so there's this guy who likes me and I like him. It's blatantly obvious to anyone who hears our conversations. He hasn't asked me to be his girlfriend yet, but he's definitely working his way there. My only problem is this: I'd love to date him, but I'm the girl who immediately goes to 'Well what if he dumps me?' {and no, it's not like I'm expecting him to marry me or anything} once I'm with someone. I don't want to constantly think about that, so what should I do? :P I feel like a total loser having to ask for advice about this on here.

Hmmm... my advice would be to... not think about that! xD nah... I'll be serious.
...actually, I'm not really sure there's much I could tell you. I think you just have to realise that he likes you enough for you to be his girlfriend. and that means that he won't be dumping you so soon. unless he's a jerk. :| and even if he WERE to dump you, it wouldn't be the end of the world. though I won't deny that would suck. ._.
hm. I'm trying to be helpful but I'm not very good at it. xD
think about it this way:
so hypothetically, if he was to dump you, would you rather have two months of bliss with him or none at all and have to deal with the what if? idea for awhile?
yeah, it's going to hurt when you break up, but seriously. if you don't plan on marrying him then it's going to happen. give him a chance. it's unfair that you wouldn't have a relationship with him because you're afraid of commitment.
besides, if you go through life with that attitude, you'll die single and that would suck.
You sounds insecure, and that you would need to work on. Insecurity can destroy a lot in a relationship, especially if you act out on it without your boyfriend understanding what happens.
I can be insecure now and then too, but my boyfriend knows it and knows how irrational the insecurity is. If he hadn't known, I'm sure he would have dumped my ass long time ago :p
What do you think about him dumping you?
Because both times I went out with someone, I immediately thought 'Don't get too attached, he'll be gone soon. I know I'm going to marry this kid.' Which the first time, he dumped after a week. I basically live with, 'If you can't feel, you can't get hurt.' I felt sad for maybe 3 hours when he dumped me by text on a Monday morning. Right now, this boys likes me and I'm going out with him and he hasn't dumped me yet so idk.
I would just try to say, even if he dumps me and I feel like an idiot, it'll be okay. I'll go on, find someone better and keep going. To enjoy it now, just say I'm having fun right now and don't think about the future too much.

It's probably just because you're still new to dating. Just try to focus on now or you'll ruin it for yourself.
Why not try casual dating? There's a lot of pressure when you focus on "steady" dating.
Usually, when it's more casual- meaning you two aren't necessarily exclusive to each other, but still date- it's a lot easier and you have more fun. When one breaks up with the other it's not as big a deal as it might be because you weren't so closed to the relationship you blocked everything else out.
Try it for a while and if you find you two have connection, then go more exclusive. When you do it this way, chances are you enter into a serious relationship more relaxed about what could go happen that you worry less about it because you already know how to connect to one another on a romantic level.
i think you are right in thinking the way you do. however that shouldn't stop you from enjoying it while you can. rather like knowing you are going to die... so live life to the fullest and all that crap.

I'm a huge worrywart too. As long as he likes you and shows you that he wants to be with you, then I don't think you'll have much of a problem. Confidence is something that grows with time, especially if that person really shows you that they like you.

Don't worry about getting dumped, it happens, but it's nothing to stress about. ;) Enjoy your time with this person while it lasts, and try not to dwell on when it will end.
I feel the exact same way as Lauren, I would rather take the opportunity with this guy than have never experienced it at all. =]
