According to the relationship experts at exboyfriendrecovery.com, you can know he misses you when he does one of two things: he erases all traces of your existence from his life. Regardless of his first reaction, you will ultimately hear from your ex again. If he leaves no trace of you in his life, then you were truly separated.
Alternatively, if your ex doesn't do either of these things and still lives with you after the break up, then it's obvious that he is still thinking about her and misses her presence in his life.
You can also tell if your ex misses you by observing his behavior around you. Does he act differently than before the break up? For example, if he was always crazy about you but now acts like he doesn't have time for you, then he is missing you.
If you notice any change in his demeanor or attitude, then you should ask him why he has changed. Perhaps, he has realized his mistakes and wants to rectify them. You must give him the opportunity to do so.
If you aren't ready to get back together yet, then there are other ways of telling if he misses you. For example, you can miss each other if he stops calling you or checking on you regularly. If he ignores you completely, then you should probably stop wasting your time.
Missing your ex is like passing past that empty area and remembering the art that used to be there... and then walking past it again... and again. Now that you know WHY you miss your ex, let's talk about some of the specific conditions you could be dealing with and how to deal with them.
If you are missing your ex all of a sudden--within a few days or weeks--then something has caused him or her to leave you up until now without incident. You can probably assume that this will happen again unless you have done something to change your relationship with him or her. If you suspect that you might be at risk for violence from your ex, seek help from a domestic violence program immediately. Otherwise, you might not get another chance to leave.
If you have been missing your ex for a while and he or she hasn't contacted you yet, don't worry about it. It may take them some time to settle down after a break-up. As long as they aren't causing you harm, we don't need to intervene. However, if you aren't hearing from your ex and something feels off or wrong, then go ahead and contact a local law enforcement agency or family services group immediately.
It is normal to feel sad, angry, and confused about what has happened to your relationship. These are all natural reactions to losing someone who has meant so much to you.
There is no single definitive solution to this issue. It may be determined by the nature of the split. If the relationship was long and loving, and ended on a sad note, men begin to mourn their partner very immediately. They might feel empty without her in their lives, but that sadness can be quickly replaced with another feeling: relief. As far as they're concerned, their partner has moved on with her life, and now they can move on with theirs.
If the break up was very bitter, then men might take a while to get over their ex. They might still think about her from time to time, especially if there was some kind of unresolved conflict between them. But she's not going to pop into his mind every time he sees something cute or feels like having fun with his friends. That would be crazy!
As for other people's opinions, well those are going to vary depending on what type of person each man is. If his partner has gone out with other men since the breakup, then he probably missed out on some great times. However, if that same woman finds you attractive, even if she's with someone else, then he should feel lucky to have had her in his life.
In short, the answer is yes, men do miss their exes. Even if they've moved on with their lives, they might feel lonely sometimes.
