Why don't people like too nice people (honest answers)?

I don't get it. I'm a very nice kind and too nice person and my best friend, close friends and family don't like it. I though you're suppose to be nice. I try so hard to be kind, nice and very nice but some people are difficult to please. My best friend told me I'm trying way too hard and I'm being fake and stop. She told me I'm so boring that it makes her wanna rip her hair off. How am I boring? I'm just being nice. My dad hates me for being too nice and slapped me with reality. He said let people do all the work in chosing when we have outings and I'm being lazy. I leave things unsolved and I always butt into conversations to be nice.
I had a date but I wasn't ask for a second one.
