Does she really care about me?

I met this girl in December before we went home for Christmas break (she even asked for MY number, only time that's happened). She sent me the occasional text to see what was up over break and we promptly started hanging out when we break was over. One night she came home with me after a party and we hooked up, the next week we spent every night together, but after that our relationship was been marked by a declined interest in making time to hang out with me. she says she's still interested in me, but i feel like she's always coming up with excuses for why we can't hang out- like she has too much HW, or her ex is around, so on and so forth. i got mad at her recently because i feel like she's ignoring me for her other friends and disregarding my feelings, to which she said i was suffocating her and being crazy. she says she still wants to try but i'm worried im just going to be hurt more if we go on. what should i do?
