Hi mommalicious,

I think you observed correctly that by unblocking him you are hoping that he will contact you, you’re leaving the door open for him to come back to you.
But the truth is that if at some point he really wants you back and is sure of it, he will find a way to communicate that to you. In fact, he will not rest until he does. Remember all these silly romantic movies with the guy running in the street just to tell a girl how he feels about her before she gets on a plane? Well, it might be silly and exaggerated and I really don’t like romantic movies, but I think that these scenes are a metaphor for how we feel when we know we love someone and want to be with them. It becomes the most important thing in our eyes, to communicate with that person, just like you said “he’s like a drug to me”.

The reason I’m saying this is to make you see, that unblocking him will not improve the chances of him coming back to you. In fact I believe if anything, it makes it less likely to happen. So my advice is, block him so that you can get on with your life and so that he will understand that he cannot change his mind on you whenever his mood changes and you’ll still always be there for him.
If he really loves you and overcomes his issues, then he will find a way to communicate that to you. After all, you’ve made it very clear that you were interested in him.

I know how these things works, at some point you might think, “well what if he does want me back but because I blocked him he cannot get in touch/will think I’m not interested”. No. If he really wants you back, he will try anyway and he will find a way to speak to you. So don’t worry about that.
Block him and move on.
