Getting in a relationship is a serious matter, and there’s no doubt about that. It means dealing with each other’s likes and dislikes, it means giving each other the right amount of respect that they need. If he’s really into you, he’d accept you completely as you are. There may be a few things that you wouldn’t agree on, but if it’s for the person whom you truly love, it would be easy to compromise and respect their interests.
But if a guy clearly says that there are only a few particular things that he likes about you or needs in you, then it’s a clear sign that he’s not into you in a real romantic way, if he only likes you because you’re this or you’re that. If a guy is really into you, he would like you even if you’re this or you’re that.
