Search Results: not returning phone calls

E-met a very attractive guy on a dating site (over35 yo). We seem perfect for each other and match as far as our looks are concerned. He has been divorced for 5 years but shared with me on a phone call that he still does not know why she left him and it was obvious that he still has at least SOME feelings for her that have not had any closure.

We talked for a couple hours and he told me both times I asked if he needed to be doing something else "you're fine". We hung up when he had to tend to his teenage son (very attached to him). He didn't return the call... a whole day passed and nothing. However, I was fully aware that he had his son and wanted to watch a certain ballgame that day too.

The following day, I was on the dating site and he logged in too a bit later. I waited for a while (about 40 minutes to an hour) then sent him a nice message that was a apology if I had worn out my welcome by keeping him on the phone two days prior while his son was there. Nothing more than that... and certainly not any indication that i felt one way or the another. Just a simple one line message.

Keep in mind, we exchanged phone numbers two days prior as well. His reply to me was "you're fine, I just had my son... I do not get time with him often... no worries."
We texted some small talk and he said he was going to go to bed and asked what I was planning to do. I relied that I was going to stay up and watch the National Championship football game but ended my comment with "if you want to meet and talk instead of talking on this silly thing (dating site message utility) you have my number." Told him Good Night.

One other thing to note - he told me his mom set up his profile because she keeps telling him he needs to find someone. He does log in often though. He has never initiated anything first... always me. I am the one who originally said something to him in the first place.

So... is he shy, just not that into me, or just still hung up on her?

My date supposed spend birthday night with me on Monday. But he worked up late , so he couldn't make it.
after he said he stuck in work he asked me if we can have a proper dinner yesterday instead right away.
I had plans and and also feels a little bit upset since he knows it was my birthday I expecting to see him but still blow me off.
so i answered it fine , i have plans.

then after one hour i think it not his fault , and he wants to make it up to me , so i text again said i may free after 9, and i will let him know.

but he did not return my text and phone calls since then.
I know he wan't busy or lost his phone.100% sure he just simply ignore me.

he never like this before, and last time we meet was still sweet and romantic.

I am not sure he doing this because he get mad because i reject his offer or just want to end it with me?
