Obviously, breasts will sag more as you gain weight, but everyone is different. I've known thin women with average breasts that sagged a lot, and I've seen some pretty obese women with perky ones.

I have known a lot of people who have had WLS, unfortunately some died from it. But those who did not, regained the weight. There is no long term method to lose weight and keep it off. Of course, everyone is free to try if they want. And everyone if free to believe that WLS works. But I have yet to see it.

Losing weight is probably one of the unhealthiest things you can do. One out 171 people get down to "normal" size and actually succeed. Everyone else ends up gaining more than they lose. Some people have to avoid certain foods, like sugar, fats or salt. Look up "health at every size." If you can't stand being told to lose weight, then gaining on purpose is not for you.

As someone else has said, the loss will be only temporary. But the real problem is that you are going to be with someone who hates being fat. As you become more turned on as she regains the weight, she's going to be more miserable, and it is not fun to be with someone who is miserable.

You pretty much have to decide between the two.

When people lose weight, they lose muscle and fat. When they gain weight, they gain only fat. So yoyoing will cause a higher percentage of fat at each cycle.

I kept getting hit on for money. I was looking to make friends, not buy them.

Breast size is not the same for thin women, therefore it is not the same for fat women.

I would think it is more about what you like. You can be into one or both, but it usually is not a decision. As far as wardrobe, I personally like to see women wear loose clothes to allow room for gaining.
