I didn't mention it because I didn't think it was important. I just assume that's how he may feel. I have no idea. If he were to read our messages it's just me responding with a blue thumbs up or "all the best".
I promise I am not trying to pick on you so I hope this advice is not coming across that way. I will just say this and be done...
With matters of the heart, you will be surprised how things you've labeled as "unimportant" have a way of driving a wedge between you and your SO. It's amazing how those little things that you fail to mention can be viewed as a betrayal.
An assumption is just "disregard of feelings" dressed up in a fancy costume, and also one of the biggest relationship killers. When you assume things about your partner you rid him/her of a voice and yourself of a genuine learning experience.
You've already done the right thing by blocking your ex on Facebook, but if he finds other means of contacting you, your SO needs to be the first to know.
