<human>: Give me a shortened version of the text

I am really bad with relationships/dating.

During high school, I somehow managed to a girlfriend. We were together for about a year and a half, but we broke up when we went to separate colleges. 

It's about a year later, and I'd love to find a new girlfriend, but I don't know what to do. I know that I am supposed to join clubs/social events, go to parties, ect. but I've been doing this and I don't feel like I'm having any luck. I even joined tinder but have not seen any success with that either (though I use it pretty sparingly- perhaps once a week or so).

I think that part of the problem may be that I don't know how to initiate a relationship. In my last relationship, my girlfriend kind of got everything going and I just reacted. Now, I don't know what to do.

How do you determine who to ask out? There are a couple of attractive girls in my classes, but the ones who I know I worry about asking out because I wouldn't want to mess up our student to student relationship.

How can I tell when somebody is flirting or "giving hints" or just being friendly? I always default to friendly and sometimes realize later that they may have been flirting.

Finally, I am starting a job for six months around the middle of September. My job is roughly an hour away from where I currently live, so I am moving to the town where my job is. Should I wait to try and find a girlfriend until after I move?

If you have any other reasonable advice, I'm all ears. If it matters/provides context, I am not overweight, wear glasses, and major in finance/econ. I did the whole gym thing for 3 years in high school (I was a wrestler), and am glad I don't spend time doing that anymore, although I recognize that I would look more attractive doing so.
