How long to be “patient” with him

[Not-so-sure]

I am in a very interesting part of a relationship with a new guy I have started dating. I am not sure what to do. 
 

I met this guy around the middle of February. We have been dating, but moved very fast. Everything came to a halt about 2 weeks ago when he was faced with a family crisis. We also had a big fight that same evening. But we were able to work things out. 
 

He is really struggling with the family issue and has asked me to be patient with him. I have been and will continue to be, but how long is being “patient” appropriate? 
 

We do really care for each other and I am hoping he’ll come around when things calm down again, however long that is. 
 

i am not sure what to do. I worry I will never see or hear from him again, and I also worry that he won’t come around. I know this is anxiety, but because I really like him, the anxiety over it is overwhelming. 
 

The rational side of me knows there isn’t much I can do at this point and my being anxious about it will only serve to make things worse. 
 

But for the mean time, how do I proceed with this? I told him I will continue to be patient with him. I know he will soon travel to spend time with the family member the crisis happened to. I worry he’ll be gone a long time, or that he won’t come back. 
 

But, I want to help him right now. I do want to be there for him and I wish I could get rid of this deep anxiety that I have about never seeing or hearing from him again. He does seem to really care for me and I think he wants to be with me. I am hoping that things calm down soon. 

What do I do about this and what are the boundaries of “being patient” with him?

At just 1.5 months in, I'd chalk this up to "it's not working out for me" and move on completely.

When you meet the right guy, you won't feel so anxious and unsafe/insecure/fearful of what might happen once he is out of your sight.

What is the family issue? 

I would not wait around for someone you have only invest 1.5 months in.   Move on.

Depends on the family issue.
