the fact that he is seeking therapy for his depression is great - how many Guys do you know who will do that without the sky falling down on them?

he seems worth looking into a bit further.

he may be depressed, but he's damn sure smart!

you may want to ck out what depression is, and your obvious repellant 'thing' going on.

could be because he's vulnerable?

and you have every right to love whoever you please, so think about when this Guy is on his feet will you waltz back in, (if you leave) - that would be awful, see?
