If you've talked to him about the situation many times and nothing has changed, this is a clear indication that the situation is getting no where. The only thing that is changing is your perception of the situation. Your boyfriend doesn't see himself hanging out with his best friend as a problem. He views more as you being the problem when you're trying to interfere with the kind of friendship that they have. In a male perspective, we tend to learn through past relationships that friendships are more valuable than relationships. It's not as difficult to find a relationship, but it's not an everyday thing where you develop a best friend. Best friends tend to go way back, and there's a lot of flexibility in the friendship where we don't feel caged like we do in relationships. In the end, best friendships tend to last longer than relationships...so we tend to hold those closer to us than relationships. The fact that he gets bored of you is a clear indication of incompatibility; as a result, he's obviously going to spend time doing things that are fun...in this case...spend time with his best friend. The only way you'll get him to spend more time with you is by doing the things that he finds fun. Essentially, you'd have to become your ex-boyfriend, Blake. However, that's a problem because:

1) you find your ex-boyfriend annoying
2) trying to act like someone you're not is only going to drive yourself to become more un-happy with the relationship than you already are.

Your boyfriend isn't gonna stop spending time with his best friend unless he somehow decides to do so. There is no convincing him, or trying to compromise. The only way he'd compromise is if he feels that spending time with his best friend is a problem and I'm fairly convinced that he doesn't see at such. If he spends a certain amount of time with you and you're both able to get intimate, he may feel that he doesn't need to do anything more than he does already. You and him have been together for over two years, and that must mean SOMETHING was going right at SOME point in time. So here's the issues:

1) You want your boyfriend to spend more time with you, but he isn't.
2) You can't accept Blake as his best friend because of your past relationship with Blake.
3) Your boyfriend gets bored of you...which indicates an incompatibility issue.

Regardless of whether you feel your feelings are justified or not, this is a situation where you gotta "put up, or put out." You either accept the circumstances, or you find another man who is willing to spend more time with you than with a best friend. It seems that what your boyfriend and Blake have is a beautiful friendship because they can relate to one another (hence why Blake's ex-girlfriend feels the same way you feel...Blake and your boyfriend are, deep down, the same person). If you genuinely love the guy and feel you're willing to make a sacrifice to accommodate his needs to spend time with his best friend, then you gotta do the same thing: spend time with your best friend, or friends. While he's spending time with his friends, it's no better time to go out and enjoy time with your friends; otherwise, he's gonna be having fun playing video games with a best friend, and you're gonna be stuck at home watching movies by yourself wondering what he's doing and talking about. Those kinda thoughts and curiosities lead to that psycho girlfriend. The more you worry about it, the more it consumes you. There's a clear imbalance in the relationship and at this point...I think it would be in your best interest to break off the relationship. If you feel he doesn't spend enough time with you and he's unwilling to provide that time you need, he's not satisfying you. The longer you stay unhappy with how the relationship is going, the more likely it is to fail down the road: either he's going to realize that he doesn't really need you in his life, or you're going to realize that the relationship is getting no where and the relationship has changed for the worst. Automatically, I'll admit, the fact that he gets bored of you is a BIG red flag and I think the relationship is doomed down the road anyway...and the incompatibility issues is what's gonna cause the relationship to end. I'm sure there are other issues as well, but that's probably going to be the main issue.

Essentially, you're either going to accommodate his needs, or you're going to find someone else. The choice is yours; I know either way it's gonna be tough, but you have to decide what is best for you and not what is best for the relationship.
