There is no definite answer to this question, as the success of a relationship after no contact depends on a number of different factors. These can include how long it has been since the breakup, what led to the split in the first place, and what each partner hopes to achieve by getting back together. However, if you feel like no contact is the right strategy for you, it may help you to work through some of the challenges in your relationship and to improve your chances of getting back together with your ex-boyfriend.
