I don't know what I'd do if someone I loved and cared about said those things to me. It would kill me. I think pegasus made a good point that you need to look whether this guy is really right for you.

Although my bf is not the most understanding person in the world, he does try and does support me as much as he can.

If what your bf is saying is only a chip of what he says/does to you, please reconsider this relationship. It doesn't sound like he even cares that much about you, IMO.

Take care and do what is right for YOU.
