I broke up with my boyfriend yesterday who was also my best friend. Now I think it was a mistake and I'm left feeling shattered and hopeless. He already wants me back home and wants to fix things. What do I do?

Ask yourself why you left in the first place? If the reason for that has changed then return and see if you can work it through, if not ask yourself whether you are returning simply because the relationship is "what you know," rather than "what you need?" Leaving can be scary but rarely does someone leave for "no reason."

Has anything changed since you decided you wanted to break up with him?  If not .. Why do you think staying with him is the answer.  Don't stay with someone just to have someone .. Or to have comfort in your familiar feelings.  I'm sure you had a reason to break up.  You deserve happiness, I hope you can find it.

I am assuming you are the same "anonymous" who wrote about what if your gut was wrong and your heart was right. Either way my answer is still the same.....

If you think you made a mistake and made the wrong choice remember this..... "though you can not erase the past, you can always change your future." Use what you learned and make it into something great. If that means getting back together and being stronger then ever so be it. If it means continuing on and learning from your mistake so you don't repeat it in your next relationship then so be it. You have the power to change your future!!! :0)

I repeated the answer just in case you didn't catch the other question! LOL!

There is no specific piece of advice that anyone can give you at this point. You chose to leave instead of work on your differences. Typically the choice of leaving is exercised when all else has failed. So .. If you never bothered to try to salvage    Your relationship before you chose to leave .. Why would you want to now? What has changed? Do you regret the choice you made .. Or were you counting on the theatrics of leaving so you could enjoy his "begging" you to come back?

I'm hoping it was the former .. Not the latter. The former would be an easy fix .. . The latter, not so much
