I (20m) have a friend G, (19f) who I met at my college some months ago. she is very nice and kind and we both have a similar belief of things current so we mostly talk when we can on the phone or at school with plans to meet up after school is over. recently while I was cooking with my brother I mentioned I wanted to take an egg roll or two for G to try since I know that she likes Chinese food almost as much as me. my brother asks me "what has G done for you? has she brought you food?" this made me doubt everything. I've shared my food with her at lunch two times both times she liked it and mentioned she wanted to come to my house to eat. I don't know about her home situation or anything like that I do know she works at a pizza hut and makes money for school that way but other than that and that her sister likes makeup I don't know anything. I am having doubts about if I'm doing too much for someone I met not too long ago and that my efforts aren't being resciporated. I've always been raised to pay back what you are given "someone gives you 20$ you give them 30$ next week, if you can't do that don't take the money" sort of mentality. Can I get your thoughts and opinions since you guys are strangers and can approach it objectively? thanks to anyone who weighs in your opinions and thoughts are welcome.

I (20M) am currently interested in a girl named G,19F, who goes to the same college as me, we hit it off rather well and I'm trying to get to know her more. however recently she became buddies with someone I know, R(don't know his age), he is someone who I admittedly don't know too well but I can tell he wants G. he managed to get her number and the two are talking a lot and he's taking her to get food between classes. I just found this out not too long ago and I don't know what to do. I don't have a car, I don't know how to drive, I am broke constantly due to loaning out money to my family for one reason or another. I simply can't compete and it hurts too much, I can't stop thinking of the two of them together. and how much better R is than me. I'm thinking about cutting G off because of this, i feel some unhealthy amounts of aggression towards both of them and i can tell my jealousy will grow from here.
