I have a reputation in the family as being a ***** and cold,

I've had a problem with one other aunt but only because she's very disrespectful and rude to my mother ( my passed father) and other family members.

I love my family, I'm not like that with everyone, only if you disrespect me I will disrespect you back.

Anyway this other aunt (mothers sister) she said she doesn't have any friends, she only trusts and like family (because friends are strangers)
When she came to stay with me I tried my hardest to talk to her and like her but she would give me one word answers ( I believe she thinks I am a bad person, I have tattoos) she's quite conservative now but she used to do weed and cocaine as a teenager. I've only ever done weed.

I get on really well with her kids, but she never ever addresses me or asks about me directly,

Every time a guy would look at me she would stare at them .
I don't understand her behaviour, I'm not a bad person, I love my family to bits,

How do I show them that I'm a good person and that I'm approachable and that they can talk to me?

Do you think my aunt doesn't like me?

Its my mothers sister

I'm confused. Do you want to get along better with your family or just with this aunt?

I get along with the rest of the family now, its just her. I want to get on with her.

Is there someone else in the family whom you could ask, to find out if you are going about this in a wrong way somehow?

Sweetie, you can't make anyone like you. All you can do is try to treat them with kindness and respect and hope one day they realize that you are indeed a good person.
