Hi Laurar, I know exactly how you feel. When I met my bf I said I have too many issues that I don't want a bf right now and he was understanding, he had his own issues as I found out later (OCD) that we have been a great match for each. I was about
to slam the door on him 4 years (in april) that I would have missed out on a great guy.
If your guy is not sympathatic at all, I would leave him alone. The last thing you need is pressure of trying to feel when you don't and you just can't hide it some days.
Feel him out. Has he or anyone he knows been through an illness? If he thinks mind over matter, don't get involved either. Because if our minds could heal us, don't you think we all would have done that by now?
Just feel him out, you'll know if he rubs you the right caring way or if he comes off as a dick.
Good luck
