If you're trying to avoid someone, just act like you're checking email on your phone. It makes you look busy, which is the better alternative than purposely not looking in their direction.

It's crazy that people think she should just except how her body is now (with the weight she said she put on). It doesn't seem like op is very happy about that so why are people encouraging her to stick with a body that she doesn't like? If op isn't comfortable with her body how it is now, then she can change it with hard work, discipline, and some encouragement! Hard work looks good on anyone; gluttony, not so much.

I've gained weight since my last break up too OP, and I can totally understand where you're coming from. It has nothing to do with showing off or making someone feel like shit or miss you, it's about proving that you're better off without them, which is hard to prove to someone when you've gained weight since seeing them. Tbh, chances are, the weight isn't AS bad as you think it is, and in time, you will get to a point when you just feel "ready" to lose it. Chances are, if he still had feelings for you he'll still miss you anyway even with the extra weight, he's moved on, or he was a jack ass to begin with if he's judging you on your weight gain.
