Dear Ms. Sassy,
I love my guy but I am so angry at him. I feel like all he ever does lately is make excuses, excuses for coming up short. I've gotten to the point where I don't feel like I can depend on him. Anytime he tells me he's going to do something the first thought I have is, "Yeah right, don't hold your breathe because he's totally going to flake on you." I love him, more than I've ever loved anyone but I can't handle the constant disappointment. Should I cut my loses and move on or chalk it up to immaturity.

Ball Crusher,
Believe me, I understand being so angry at your guy that you want to crush his man-meat. But leaving him unable to reproduce won't solve the problem. You say he offers excuses for coming up short, which leads me to believe that he's at least making an effort. And if he's at least doing that much then you should talk to him. If I've said it once, I've said it a thousand times. Guys are dumb, and unless you communicate the severity of your feelings or how his actions, or lack of actions are affecting your relationship then he won't know that he needs to get it together, and fast.
Talk to him and let him know what's up. Let him know, very plainly, that you are unhappy in your relationship with him and his lax approach to keeping his word is making you think that you're wasting your time staying in a relationship with him. He'll either take what you say to heart, which means crisis averted, or he'll keep doing what he's been doing. In that case kick his sorry rear to the curb, and maybe work in a hit to his junk. Hey, in that case he's got it commin'!
