My boyfriend is mad I had to buy bigger clothes.

So I’ve gained a bit of weight recently and honestly I feel ok with myself I’m 116 ponds and although it’s a little more than my typical size I feel comfortable with it. Well today I had to get some more leggings because mine are just too tight around my waist. He is mad ... so mad he won’t even talk to me and when I brought it up he said “I just don’t understand why you don’t do something about it instead of buying new clothes. Why don’t you just start going to the gym?”

I really don’t know what to think of this. He tell me he thinks I’m beautiful but I really don’t think he means it or else why would he say that? What are your guys thoughts?
