Am I petty for not answering my ex friends messages?

So I’m going to make this as short as possible but me and him met at a festival last year. We vibed very well and we even went to a camping festival together. The experience between the two events was extremely different and I ended up not liking him after the second event. He was very condescending towards me and made me feel crazy whenever I even just spoke. He used to pick at me because I was overweight and basically used to tell me it was unhealthy (fine) , but it seems like he would get condescending if I didn’t take his advice. He always had a “I’m always right” attitude. 7 months past by, we haven’t spoken , he removed me off of Instagram. He then saw I dropped weight and has been nonstop hitting me up. I decided to give him a chance texting wise, but he still comes off very condescending and seems like he only hit me up now because he thinks I’m hot after the weight loss. I am no longer interested in this friendship as a lot of time has gone by and seems like his friendship is conditional. Am I petty for ignoring him?
