<human>: Can you provide a brief rundown of the text in within 3 sentences?

I was in a relationship with a girl for about a year(our anniversary is in 2 weeks) we ran into some problems around august.(mainly my fault) I let a girl kiss me and stopped her before things got out of hand(I know its still not an excuse).

Then we went on a break because my grandmother passed away and I needed time to reevaluate my life. She got used to not having me around(as she told me) and didnt want to continue the relationship.
She didnt want to deal with my family issues and problems and worrying about me.(I can see how it can be stressful)

I know I cant make her love me and I want her to be happy. but I was hoping that talking to her in a week or two and asking her if we can hang out might work or if i should just give it more time. I wanted to treat her out to something nice and work as a friend from there.

I have our anniversary gift(it was an engraved necklace) that i wanted to give to her but Im not so sure about what to do right now...
<bot>: Fucked up my relationship, trying to mend it through kind gestures and time(as a friend and then onward), need advice.
