I'm Too Nice

I'm a very nice, soft and kind person. I expected everyone One to be as kind as me and have the same heart. I always her hurt in the end. My dad has been trying to snap me into reality and get out of la la land. He's been hard on me because if my too niceness and I'm too nice to stand up for myself. My ex broke up with me becauae I'm too nice and I tend to agree with everything to make him happy and he told me I'm Passive aggressive which annoyed him and threw him off. My friends don't like I'm being too nice because it I expect too much from people and being overly nice. I agree to make others happy and when they don't say thank you or be nice, I get hurt and dissapointed. My mom said, "You can't expect a thank you all the time. There will be people that dont appreciate what you do for them."
One time I was crying to my mom but she moved away from me. My dad told me to stop the too nice shit and said, "Stop the crying and buck up! Snap out of it! People will be assholes okay? So GET USED TO IT!" He can he blunt sometimes.
