Why does everyone say I'm too good for him?

This doesn’t seem to be good, could be simple disapproval of the relationship between your friends. Its not right and they seem to want to pressure you out of the relationship.

This can cause several hardships, for one, if a lot of people are saying it eventually your boyfriend is going to fall for these lies. This can eventually be very problematic, hes going to end up doubting what you say to him, believing any story that pops up. That might or might not happen, the important thing is to remind him that your feelings for him are genuine and that nothing that these people say is true. He might end up being very self conscious about this but remind him that your the one you want.

As for you, instead of arguing with the people that say that your to good for him, try to understand why it is that they’re saying that. Work out a plausible solution, they have no right to be interfering in your personal situations unless you want them too, on top of that they have no right to be trying to force you two apart. Listen to what they’re saying, it could all just be biased opinions with no real thought. Simply to stir up some unneeded action around your school or between your friends. I hope that people will understand that you know your boyfriend better then they do and what you say should be held higher then what strangers or their thoughts say.

And dreams are not (from my perspective) a premonition of something. Like I said earlier, you know your boyfriend better then other people do and you know for sure based on what he tells you about himself whether he is likely to cheat on you or not. If you guys are very open to each other and trust each other then there is virtually no chance of cheating to happen anytime soon (from what I know). If someone does say he cheated on you (which I feel might happen) then ask them how they went about finding that out?

If nothing goes right then you don’t need to listen to them. Its your relationship and you and your boyfriend are the ones in charge, not them. Remember to stay strong and keep your head high!

I hope this helps and good luck!
