Yes that's true but if you want to get your blood sugar in control quickly going keto which is low carb is the way to go and then control your intake

He has diabetes so ya I would make that switch.

Oh for sure. I was in OP's shoes with a T2 diagnosis. Although mine was official. Doctor offered medicine and I said can I just change my diet + exercise to put it into remission. He said yeah your young enough to try. Honestly as a dude that spent most of his early life playing rougher contact sports, I put cardio to the side and just pumped. It helped my fat loss but not at the rate I wanted. I was getting and am hella strong now. But I've added more cardio time and the combination is doing wonders.

You're both not wrong.

Swimming has been touted as one of the best exervises for awhile now because of the resistance.

That being said, it won't make you stronger. It depends what your goals are as well. If it's purely weight loss, either works. Weight lifting is important to incorporate as muscles end up using more calories to maintain. But most of all you want to have a decently strong body just for your future. There's benefits to all of these things. It's whatever you enjoy most.

I actually wrote like 2 paragraphs about openly talking about the situation with him and being direct without sugar coating it. Which I still believe is the correct decision.

But as a person who's rebounded and has been a rebound. There's nothing wrong with that and the stigma placed on it isn't really true half the time. If you're in a shitty relationship and it ends why wouldn't you want to go next. Some people decide to live single for a bit, I did that after one relationship. Some people already see a failing relationship but aren't driven enough to end it till the other person does, at this point both parties are looking for the next.

She didn't break up with him out of the blue. Dumb arguments etc are signs of a failing relationship. Sure they happen in all relationships, but if you're venting about them rather than joking; I feel like it's on a dead course. If you're worried about being a rebound, you're correct in thinking that. But you've made your move, regardless if you're happy with it or not. You like the guy. Just have an open conversation about how you liked the person he was and not who he is now. Straight up ask why he is like that. Remember that you were his pseudo-therapist and now he can't say things about you to you.

Rebounding doesn't automatically mean a doomed relationship.
