Should I change how I dress?

to summarize me and my boyfriend have been dating for 2 years. I've always dressed normal, maybe revealing when i go out during the summer, but over time I've gained weight so my boobs are bigger so i obviously have more cleavage. he saw this before we dated, he saw what i posted on instagram and yet when i go out now with friends wearing a tight dress or show cleavage its ALWAYS a problem. he expected me to dress more conservative when i got into a relationship? but i never had this problem with my ex. even if he doesn't comment on my outfit, its very apparent because his mood changes and then i feel insecure in my outfit. am i in the wrong? he doesn't think he's the problem? what do i do? i dont want to base my outfits based on his opinion. i dress for myself and I've always have dressed the same? should i be dressing more conservative?
