No. What someone is, and what they prefer are two different things. Some large people don't like to call attention to their weight by dating another large person. Some large people grew up learning not to like themselves or other large people. Some feedees want all of the food and attention.

Does anyone know if this will give you manboobs?

See a doctor.

There is no guarantee that anyone can get up to a higher weight, and even less of a chance that someone can get back to their old weight. Yoyo dieting is unhealthy, and people who continue to do it, end up getting less muscles and more fat as they do it.

You lose fat and muscle, but gain only fat.

That is true in all kinds of websites. People confuse fantasy with reality.

Yes.

My exwife took a bath and pulled the plug. Only the water from the front half of the tub drained out.

You and your boss got high at work, and then he wanted to make you pregnant? Sounds like he can get into a lot of trouble for that.

Do a lot of non verbal things. Don't say how big her tummy is, but touch it and then just say a lot of nice things about her. Perhaps tell her you like the outfit she is wearing, or the way she smells. Then slowly make comments saying something that her bra is getting small (rather than her body is getting bigger.) By now, if she is still into it, she may like you saying that you like her gaining.
