Should boyfriend's tragedy stop us dating?

Dear Mr Bitter Guy, I need dating advice ...

Ok, well long story as short as possible....

My bf and I have been dating for 2 months... he is BY FAR the most amazing man I have ever met and yeah yeah I know its always good in the beginning.....

Well he had a son that passed away in a horrible accident 2 years ago. So his son bday was August 28th and his sons death was Sep 30th when he was only 2 so I am sure you can see that this month and a half or so is really really hard for him and VERY stressful.

He is a really kind laid back guy and he has been VERY stressed and very depressed recently. We had a talk the other night that he said he cannot handle a serious relationship right now....reluctantly I said fine I will go home and he BEGGED me to stay and please just "bear with him" through this hard time he is going through. He said he still wants to hang out and go on as normal.... he says i am the only one who really understands what he is going through (bc I myself have delt with and am dealing with severe anxiety). Hes so confused right now, he feels like not having that "Label" will take off stress of him worrying about making me happy all the time on top of everything else he is dealing with.

He is starting therapy and probably medication when he goes to the therapist next Monday. So he is taking steps to make this time of year not so hard.....

So my question is, am I stupid to wait and help him and be there for him during this time as a friend and once things get better we can pick it back up? He states that he just is in no state of mind to give me what i need but he knows how lucky he is.... I made him promise if i did this that there is no dating other people bc i wouldnt be able to handle that.... and he promised me and said thats not what this is about...he just wants us to be able to have a healthy relationship....

I just came in his life at a bad time.....

I love this man... he is amazing... but would you wait???? (im not talking years, just a few weeks to a month too see if he is getting better) I would hate to leave him in this time of need.... I just dont know....
