Am I just a "convenient boyfriend"?

Sjcash
Me and my girlfriend have been dating for almost 2 years now and we would talk all the time! But now lately the last month or 2 or 3 during the week she hardly ever talks to me and I would text her after She gets out of school and... Nothing... I'm lucky to even hear from her. She says she did not hear her phone or she was watching a movie or homework... ECT so I talked about it and this is what she said... "I feel horrible when you tell me I seem to put you last because I think subconsciously I realize it but it isn't intentional at all and sometimes I need to be reminded and I know that isn't fair to you because I know I don't like to feel like I'm on the back burner either" OK but I'm like OK maybe we all need our space but she was like no I don't want space. I just hate being the "convenient BOYFRIEND" there when she needs me but that's it... Our weekends are great! We spend everyday with each other and I buy her stuff for her car and I pay for dinner and stuff but after that it goes back to like nothing. Just kinda unappreciative cause of comments like "i wish I had better subs" Right after buying her a new set of subs and huge Amp not one freaking day later! They sound a hell of a lot better than the last set OF Nice subs I bought her too! I Try but I'm just not good enough. I love her so much with everything I have. we have a "fairy-tail relationship" no really fighting never broke up, and she loves me but I don't know what's going on. Help? I just don't know anymore I'm about to give up.
