Everything is possible. Normally should be the other way round. For man, 20 years old will still have a kids mentality. And most probably he likes the 35 year old women is maybe because the women takes care of him like his mother. How long has they been together. If just a few month, then still cannot see the problems yet. But who knows, sooner or later, there might be or might not be any problems after all.

Then I guess you know best how is your relationship. There is no rules on how old both have to be in order to be in love. Oh and if can, need to prepare for marriage soon. Because women at 35 is nearing the danger zone of having pregnancy complications as they get maturer. Unless if she is not planning to have kids then is okay.

No problem. Good luck and all the best to you....
