Feeling completely ignored by someone you just broke up with is not a good feeling, but you shouldn’t take it as a personal attack. Even if you ended things with a common agreement, things can still be weird for a while.

If he seems to be going out of his way to not talk to you, the cause is probably one of the most reasons why your ex is avoiding you. Take a look back at your breakup and decide if your ex falls into one of these categories in order to figure out why your ex won’t talk to you anymore.

1. He’s Still Not Over You

Whether or not he seemed fine with the breakup, he may have reconsidered his feelings and finds that talking to you isn’t really pleasant. If you’ve initiated the breakup and then pushed it into the “let’s be friends” dynamic, give him some time to cool off. He might still have trouble processing his feelings and if he’s not completely over you, don’t keep trying to contact him.

2. He Lied About Wanting to Stay Friends

Sometimes the friend part at the end of a breakup is just a polite lie that’s meant to help everyone avoid an awkward moment. So one of the reasons why your ex is avoiding you might be the fact that you’re not trying to pursue that friendship which he doesn’t want or need.

3. He Doesn’t Want to Hear About You Moving On

Even if he’s over you, he might not be interested in hearing about your new relationship. Keeping his distance could be a defense mechanism or he simply wants a clean break. Even if he proposed that you stay friends, give him some space and that might happen eventually.

4. He Doesn’t Want to Return Your Stuff

If he owes you money or you’ve left valuable things that he also uses at his place, that could be one of the reasons why your ex is avoiding you. It’s a bad thing to do, but it’s especially common if you’re the one who initiated the breakup, leaving him no say in the matter. Reach out to him in a non-confrontational way, and tell him that he’s being unreasonable if that’s why he doesn’t want to talk to you.

5. He Might Have Been Hurt More Than He Let On

When you leave a guy broken hearted, he definitely does not want to you again, at least for a while. He might have put up a brave front when you dumped him, but the though of seeing you again might be too much for him right now. Don’t be upset and just give him his space, especially if you want to end up friends in the future.

6. He’s Already Moved On

One of the most common reasons why your ex is avoiding you is that he simply moved on. He wants to focus his energy on his new relationship and just doesn’t want to “waste” time on you anymore. Some men might be considerate about this, and avoid you thinking that you’d be hurt if they moved on so fast. But if his status relationship changed on Facebook, let him enjoy his new thing and he might actually apologize later on.

7. He’s Dating Someone You Know

The option you really don’t want to consider when your ex is avoiding you is the fact that he moved on with someone you know. This can be particularly tricky if you shared a workplace romance or have common friends. Sooner or later, you’ll be pissed when you find out, but he’s hoping for later.

8. He’s Genuinely Too Busy

One of the simplest reasons why your ex is avoiding you is the fact that he’s genuinely immersing himself in work or other projects in order to get over the breakup quickly. A lot of men like to focus on something else until the post-breakup negative feelings go away on their own. It might not be the right thing to do, but accept it, and leave him be.

9. He Resents You

If your breakup didn’t exactly go smoothly, he might be resenting you without actually acknowledging it to your face. When you notice he’s rude and dismissive, there’s no reason to try to contact him again.

10. He’s Simply Doesn’t Care What You Think Anymore

Sometimes men consider the breakup has freed them of any rules of polite society so one of the reasons why your ex is avoiding you is that he simply doesn’t care what you think about him anymore. If you talk to him again, this can be pretty obvious, but don’t be tempted to act the same way. Be the bigger person.
