Tragic Taurus...any suggestions?

I began a relationship with a Taurus recently and things have taken a turn for the worse and i have no clue why....

Here's the back story:
He has been a friend of the family for years. He is a little older than me. He approached me out of the blue with a very clear/obvious interest in dating. We talked a lot, he started learning/paying-attention-to my schedule and doing sweet thoughtful things around it (texting good morning when he knew I woke up in the mornings , calling me to and from work to chat, sweet good nights, etc.) I really liked it! We had great chemistry already. He opened up and said he was very shy but he had really liked me a lot for years and finally got the courage up to reach out to me and see what could happen....well, he and I had very mutual physical attraction and very ready and easy chemistry. We are both cuddly people and seemed to have a very natural easy comfortability around each other.
Everything was moving well in the direction you would expect when two people like each other....

Then everything changed. He has two young boys and he had some major stress come up in his life (regarding his boys) that resulted in him withdrawing completely from me. We never fought, or argued at all. I didn't do anything to him except like him back and be completely open to the possibilities....but I'm also no doormat, so I confronted him gently about his withdraw and asked him if I had done something to make him pull away. He acknowledged and apologized for the withdrawal and basically said he had a lot of things he needed to think about and needs to focus on his boys right now, girlfriends and relationships are at the bottom of the priority list at the moment...sorry. He said he really liked me a lot and that he loves talking to me. yet, he has completely stopped talking to me....I am not sure what to do.

Here's the problem:
I saw him last weekend when I was visiting some mutual friends (he was there visiting too) and he actually was very cold towards me. He wouldn't look at me at all let alone acknowledge my presence. Not even a hello or goodbye. I have no Idea how to process/interpret this because he told me that his withdrawal had NOTHING to do with me at all and that I didn't do anything, yet he's acting like this....and I did nothing to him to deserve this passive-aggressive icy behavior from him. It was noticed by the friends a

ran out of room, heres the rest:

and he wont even talk to them about why he's acting this way towards me. He's just a vault...and they said he isn't seeing anyone so its definitely weird. AND they said it was out of character for him to do this...

It really hurts and sucks because he's been a friend of my family for years and I have no idea how to navigate this. He barged into my life like a bull in a china cabinet (no pun intended), and then just left a huge void where he was. I really liked him and admired him a lot (still do) and he means a lot to me. I just don't know what to do. Any advice on how I should handle this is welcome. I am a gemini but I don't really act like one (so I've been told by many different signed friends) ....I loved the connection we shared and how interested he was in what I was up to, my life...he really was making himself a part of it...and now? Just gone....It just doesn't really add up. For someone whose liked me from the shadows for so many years to now just drop the ball like that....especially when everything was going GREAT! ...ugh... any advice is welcome. Thanks guys.
