<human>: Condense the text into a few key points

early 20's male here (throwaway acct) .  I think I've got a problem with being a "taker" when it comes to relationships.  I have a long term friendship with a girl and it seems to have evolved into a "you feed me, I hang out with you" kind of deal.  Literally every time I hang out with her I get fed, be it at at her house or out.  I don't try to be a mooch, but I'm a really cheap guy, and always hungry.  In fact I'm embarrassed by the fact that I can't afford to buy my own drinks or have dinner in a restaurant, but we both know that if I'm getting free food, I'm gonna be in a great mood, and I'll hang out longer.

It seems to work for us but now I've found yet another girl and I'm afraid I might start exploiting our new friendship/any interest she has in me romantically.  She's offering me free beer!  I don't think I can resist!  But I don't want to be a selfish asshole and end up hurting someone..
<bot>: I'm a cheapskate with a massive appetite who somehow gets female friends to feed me.  Is it wrong to accept free food and special treatment "in exchange" for friendship?
