Quite tolerant aren't you?
Pushover.
I suppose. Then again, I grew up with my mum dating as well. I didn't like the first 10 men she dated, and she was obviously upset by that. Eventually, I actually gave some a chance as opposed to finding every little thing wrong with them. Then came along the man I was talking about. When I first met him, he seemed a bit insane. Though, I gave him a chance. I saw through the insanity, and I realized how kind he was and how much my mum loved him, and I came to love him as a person and a father. He was more of one then my biological father. I'm not sure if that's the same situation here, but I happen to feel the original poster should have some patience, as its not only him that matters in this situation. A broken computer is temporary, but a broken heart always leaves a scar. He should do whatever he can to make both his mum's and his ride smooth, and if her boyfriend is a bit annoying, just talk to him.
Best wishes(At Bricky....but you too. Hm. To everyone!).
