If you are asking this question I suppose you must be worried about it. If he is very overweight then it isn't good for his health but if you love him and find him attractive it shouldn't be a problem from a romantic point of view. Maybe you could gently tell him that you are concerned about his health and think he would look nice if he lost a few pounds.
The decision to marry someone should not be based on their weight alone, but rather on factors such as shared values, mutual respect, and emotional compatibility.
Weight differences between partners are not uncommon, and there is no specific weight range that is considered appropriate for a couple to be compatible. What is important is that both partners are comfortable with their own bodies and that they accept and respect each other's bodies.
It is also important to consider the potential health implications of a significant weight difference between partners. For example, if one partner is significantly overweight or obese, there may be an increased risk of health issues such as heart disease, diabetes, and high blood pressure. However, weight alone should not be the determining factor in a relationship.
Ultimately, the decision to marry someone should be based on a range of factors, including emotional compatibility, shared values, and mutual respect, rather than weight or physical appearance.
