I feel my gf does not value me and I don't know if I am right or wrong

Me:
- I have always been there for her and supported her by all means. I never left her disappointed.
- Even when she hurt me I did not argue with her or taunt her.
- Always tell her I love her and always makes initiative to meet

She:
- Rarely tells me she loves me.
- Is distant most of the times.
- She says she has been hurt many times before that's why she is hard to get.
- Blames me when she is the one who has done wrong.
- Never asks me how I feel and never tells me she misses me
- Rarely takes initiative
- Rarely says thank you when I do good for her
