If your boyfriend left you, then it was likely for one of two reasons: Either the relationship was becoming stale because there was not enough of you in it, or the relationship was getting too claustrophobic because there was too much of you in it.
If you are wondering, how can I get back together with my ex boyfriend, then you need to start looking at which of these led to the break up so you can act accordingly, when a relationship fails, you need to take that as an indication that something went wrong.
Whatever the issue is that chiefly contributed to the split, it was probably either something that you did, or something that you didn’t do, it may be harsh to look at things this way, but that is simply how it usually works, the person who was broken up with either did, or did not do something and the person doing the splitting simply felt driven away.
So now what happens, and how can you manage to get him to come back? The first step is to change whatever it was that drove him away in the first place.
You need to sit down and really take a hard look at your situation, what could have led to the breakup? Which of these things were your fault, and which were not your fault?
Rule out the ones that were out of your control, since they continue to be out of your control, and focus on the things that you did do wrong, the ones that you can in fact change, if your biggest problem is something that you were responsible for and that you could change, then there is a very good chance that you can still get back together with him, however, you must be certain you really are willing to make the necessary changes to appeal to him again.
Just knowing how to get back together with your ex boyfriend is not enough, it won’t happen unless you are willing to take action.
