I had a big problem with the way mine would suddenly withdraw. I respect that I had a problem with it.

What I think is this--
When you feel secure with a person of significance--a friend/lover/partner, you do not need all the contact AND in fact, if you need more or less, you can just call/text or be direct and say, "Hey, not now, I'm busy. Love you."
I have been in other relationships where there was more or less calling (thank God many of my relationships pre-dated texting and even emailing) or texting BUT it was a non-issue. I remember that with each man, I would be nervous and all screwed up about the contact (waiting for a response, waiting for a message) for the first little while (like a few weeks or so) and then things would plateau and level out and it was all cool. Contact was a non issue.
I would call my bf of 7 years randomly, often driving just bored and he would say, "Honey, do you have anything to say really because I am working?" and I would answer, "No, I am bored. Just talk to me. You have to give me 5 minutes." He would sigh and do it.
What was the difference?
TOTAL SECURITY. 100% SECURITY. I was SAFE. I could be a nuisance and call 5x's in a row or forget to call, "he" could call OR not and it was all FINE.
The waiting for a call/text, the angst around, "Should I text him?" or "How long should I wait to respond?" or "His text was sort of cold." is all based in insecurity. There is nothing wrong with you Swelsha or you MissM. It is the nature of the connection.
It is not safe.

That was very helpful. thanks ladies.

I often found myself asking him if something was wrong..and I knew that rationally, nothing was. He woudl respond with 'no babe, nothing at all, why?' I always thought something was wrong, even when things were totally right. The thing is this: He would be in contact with me constantly for weeks at a time at which point i felt secure and at ease.. and then suddenly he would withdraw for a few days. Somehow, i thought I was teh culprit. How screwed up is that??
What teh hell is wrong with me?

Nothing is wrong with you.
I don't know how to advise you because it is familiar to me as well.
You have choices. If it's too angst ridden, too stressful with too many negative emotions percolating; you can choose to end it. If you can handle it, if you think it is nerves from another event or it will quiet down or things will get better; then continue.
Sometimes it is possible that people are just too different too in terms of what they want and need. Sometimes it is okay for someone not to be in touch for a couple of days and one partner wouldn't balk at it and another would be losing her/his head.
If there is too much of a power play going on, at least that has to change. For your sanity and health.

you know Creo, I remember very clearly one night. I was texting my cousin and him at the same time. This was literally a few weeks into our relationship. I was telling my cousin about M and at one point I txt her that we kissed. except, I sent it to him by mistake. teh context of that little msg coudl have easily been misinterpreted so of course, he didn't understand that i was actually referring to him. I tried to explain but he was seeing red. Remember that it was the beginning and things were highly intense between us. He has a jealous streak, to say teh least. Anyhow he wouldn't answer my texts or my calls. It only lasted about 2 hours...the silent treatment. I sent him 2 texts and called him twice. Nothing. He called that same night and came over and I told him I will not have this type of behaviour in our relationship, He aplogized but he went on to say that it will happen that we will fight and he cannot promise that he wouldn't withdraw at some point. his words: You best be not around me when I'm pissed off, I may say things I'll regret, so please don't insist if i don't want to see you for a day or 2.
As time went on and we'd fight, the gap turned into 5, 6 days...even a couple of weeks one time. It's torture.
