I have tried everything, even blocking him, but nothing seems to work. So if you’re thinking, “My ex is with someone else but still contacts me,” you now know that your ex has a reason to reach out and converse with you. But asking your ex to clarify their messages is a completely valid request. That’s unbelievable to them, how could you possibly get over them so quickly? Confusion is the last thing you need when you're trying to heal from a past relationship. If you’ve long since split up your ex-boyfriend but you’re wondering why he’s still staying in contact with you then there may be more to it than meets the eye.

If your ex keeps contacting you it could also be because they’re finding it hard to accept that you really have moved on without them. Your ex likely contacts you when he or she is having difficulties with his or her life—so your ex relies on you to absorb his or her frustrations. Meanwhile, my ex moved back home to get married, but still contacts me all the time, which I think is dangerous.
Both guys and girls can choose to stay in touch with their ex’s for a variety of reasons. But, if you show that moving on from them is really difficult for you, it boosts their confidence.
