I have bf - a good guy )) loyal, nonjudgmental, supportive...

Wow, lots of rude people here. For starters, it's normal to feel that way in relationships. Some people feel more in a few months than a lot of people do in their lifetime. Examine what is wrong in your relationship and talk to your partner about it. If it doesn't work out it just doesn't. You don't have to stay with someone just because of how long you have been together or how much money they have spent on you. If you can get what they offer to you out of any other relationship, you should probably move on. Doing the bare minimum gets boring.
