Being compatible with the person you're dating is incredibly important!

If your mindsets don't match and it is making you miserable, I think you know deep within yourself what to do.

it depends on how much you're willing to compromise on eating habits and lifestyle? or would you rather have someone who will engage in fitness activities with you and plan nutrition.

How much are you willing to compromise and settle on, I think you really must think about what you want in a partner for yourself.... otherwise you can get incredibly lonely going down a certain path in life if your partners not on the same page, at least I did.
