Well, Golfgirl, I dunno what to tell you about it - I never had a boyfriend this uncommunicative before!
He IS super-busy, and at work it's not easy for him to call or text (works with chemicals in protective gear). He's also caring for his elderly mother who is going through treatment for hepatitis C - she moved in with him just before I met him, and I think he's had a lot of difficulty adjusting from being a single guy living alone, to having his mom (and now twenty-something daughter) all living with him. Plus he has his 9 year old daughter every other weekend. I think frankly some days he's had ENOUGH of the women around him and last thing he wants is to call me and talk to another WOMAN lol.
Given all those excuses - I also think he's got some issues with getting close, and maybe the not-calling thing is his way to feel like he's still in control of the situation.
But when we're together, he's great. And when I broke up with him for a little while, he didn't run out to go out with other women - he still wanted ME. (And trust me, the way this guy looks and sings, he could pop into any karaoke bar in town, sing one song, and walk out with any woman he wanted. But his history is that he's usually a one-woman kind of guy, and I am seeing that now.)
It remains to be seen whether he can step it up a little bit. I'm really not the demanding type, it wouldn't take much to make me happy. But I've decided to just give him a little more time and see what happens.
