I think my girlfriend doesn't love me or am I just overthinking?

My girlfriend and i when we first started dating used to talk A LOT 4 months later it seems like i always start the conversations. i am always complimenting her but i never really get compliments back, she will walk up to others during school and talk to them but not me for some reason and when i do talk to her the convo ends relatively quick. can someone tell me if im just overthinking or am i slowly losing her?
