Does This Sound Right to You?

Okay i've been with my boyfriend for a year & a half now. We have a very loving relationship & are very compatible with eachother. But there is something that bothers me so much about him & i confronted him about it yesterday.

See, he works during the week & i have college classes, so we normally get together around 7 on weeknights. Then on weekends, we normally don't do anything together during the day so we just get together later on in the evening. [weird.. i know.] so basically he just sits at the house all day just chillin - to himself. which i can understand honestly because he works his butt off all week long. so on days like that [mainly saturdays, sundays.] he doesn't call me all day long until he wants to get together. it's been that way ever since we got together. i find it very odd & i asked him about this yesterday..

He told me that the reason he doesn't call me earlier on days such as this is because he's afraid i'll want to come over & he won't want me over yet. Now i think having that mindset is very pessimistic & kinda weird actually.. he's my best friend & i love him to death. But, the thing is - i give him plenty of space, plenty of alone time, plenty of "man time" if you will. So what is the big deal about picking up the phone to just see how my days going? Or just to tell me he loves me? I just can't understand that. I think it's messed up how he just assumes that i want to smother him all the time. Do all men think like that sometimes? How stereotypical is this?

So to conclude i'll say this. I don't call him, I let him call me. I give him plenty of down time to himself & do not invade on that. Let me also mention that he is bipolar. Do any of you agree that this situation is a little odd? I know he isn't "hiding" anything or cheating. That's out of the question.

He says that this is just the way he is & not to take it personally. But how can i not? He asked me "what are we going to talk about if i call you up early on in the day before we see eachother?" [inquiring that we spend a lot of time together so phone convos aren't normally 2-3 hours long] he says "it's not like we're going to have some big inspirational convo on the phone.. it'll prolly just be dead air."

but see, that's the thing. what the conversation would consist of is COMPLETELY beside the point. it's the simple fact of him taking the time to ring me up for a quick hey baby what's up. that's the thing. but guys are wired so differently than women, so i guess that's why he failed to see it the way i do last night.

Thoughts?

This is something that honestly makes me feel like crap. Even my mother has said she finds it pretty weird.

Is he just being a dude?
