Title.

When I 1st met my LTR, she was in great shape, toned, and told me she loved working out, and before we met she worked out every day.

As we spent more time together she would stop working out as much. I started taking her to my gym to get her to lift but she didnt want to.

Eventually i started worrying she would get fat and would tell her "if you get fat ill stop seeing you." Things like that.

After a month or so of me saying that, she said I was becoming mean.

Now, yesterday, she tells me she started working out again, and even started doing her little body weight routine infront of me.

what does this mean?

should i be worried?

is she starting to work out again to impress / attract someone else?

should i make her feel bad so she stops working out?

Edit: we still have hot sex multiple times every meet up. Is she trying to get me comfortable and pull a quick hypergamy on me?
