Are dumpers usually mean and likely play silly mind games?

Me and my ex-girlfriend broke up about 2 months ago. Basically she wanted more spark and aggression (I am a nice guy, she wanted a wife-beater like her ex). She hated the fact that I had friends and good sports and social life. I gave all that up when I met her as she doesn't like me going out (my mistake but learnt from it). She said there is no future and dumped me.

I was hurt but started moving on with my life. Went NC and spent my time in the gym, partying with friends and took on salsa dancing etc. I changed my clothes, style etc with the advice of my female friends.

I knew my ex was flirting with one of her old flames before we broke up. It did hurt me but I tried not to show.

I am starting to get more attention from other girls and my FB photos would show that I am looking really toned up & I eventually got my confidence back (after she destroyed me).

Suddenly she started liking my photo and added flirty comments. I asked her what was going on, she was mega nice but suddenly turned nasty after I asked her if I can help with anything let me know.

She said she finds my new lifestyle weird and feels that I will be a lonely guy as "I am not trying to build strong relations with people (friends) and making a base on those quite temporary people who don't have anything important to say".

She then said, Sorry. If I am being mean, that is me!!!

I made a lot of new friends and hanging out with them as part of my healing process. I am still hurting from time to time but she can see that I am happy. Then she called me 'loving myself too much' as I am all toned up (not chubby as she used to call me) and looking better now.

I don't think she likes the fact that I go out all the time after she dumped me. She is stuck at home because of the kid from her past but I didn't expect her to be this mean. She used to be such a lovely and kind girl but I am now seeing a different side of her.

Is that because she is a dumper or other issues?
