Need advice

I’ve been with my girlfriend for a year and a half, but I’ve been feeling drained. She gets upset if I even glance at another girl in public or make eye contact with a waitress while ordering, so now I’m constantly watching where I look to avoid arguments.

Also, I am a college student making about $150 a month and I spend almost all of it on her, but it never seems like enough. For Valentine’s Day we went to breakfast for $35 and sushi for $50 because that’s what she wanted. After that she wanted ice cream, but I only had a dollar left. She got mad, said she always has to pay for everything, and compared us to another couple saying “I bet she didn’t have to pay for her ice cream.” What hurt most is I had already spent half my monthly money on gifts for her for valentine’s day. I’m trying my best, but it doesn’t feel appreciated. She also keeps noticing other girls out in public with coach bags and keeps saying “I bet her boyfriend got her that.” It hurts because I keep trying but it’s never enough.
