Can't help you out with since I'm not sure what it means, but I'll tell you that I'm in the same boat. His name is literally every where for me, some one will say it in a video, I'll see it written down, see different "versions" of his name spelled. I used to freak out and be like WHY!!! especially since I've been on and off of letting him go or not. And right now we're on good terms but I told him I need space to work on myself and he is supportive and hoping I get better. so now when I do see his name I just smile and say "hey that's his name" and try to have just positive thoughts since I'm used to being destructive with my thoughts.

I wish I could give you a solid answer as to why it happens, maybe we're more aware since that's his name, maybe the Universe is saying don't give up, maybe we're giving ourselves the situations in which their name would pop up "randomly". What ever it is, you give meaning to it. I'd suggest giving it a positive meaning since there is nothing wrong with that. (:

Same thing happens with me. And she has a fairly unique name. 

I was grabbing coffee from the keurig one morning.... I don't drink cofffee... just had the urge. I walked into the family room, and  looked at the TV, saw her name. That is NUTS. It's like the universe was telling me to make the coffee because had I been normal and decided not to, I wouldn't have seen her name there. 

I think we create these signs. 

Every time I look at the clock, I see "33" I don't consider it a sign, as much as my own manifestation, which still, gives me hope in the LoA

Thanks everyone
I'm going to start looking at this more positively and stop worrying

I believe its because your focus is on him and these are evidences of you getting closer to your manifestation, it happened to me a lot.  So, they are good signs, it means what your doing is working!!!
