Despite everyone's worry of a woman's biological clock, some people just are not ready to marry yet. Some just prefer not to marry at all.

If ever she kacau you after you are married, it is seriously her problem, not yours at all.

It is completely understandable that you are having dreams like this now. It is quite common actually.

In fact I would even say it is a good thing. To have the doubt now, means that you have time to really think it through, sort it out, and be certain of the decision. You are having pre-marriage jitters, but it is much better than having it AFTER the marriage.

Be certain, go get married, go for your honeymoon, come back and grow with your family. Your ex is as gone as your previous job's boss.

It was not a mistake. It is good that she became independent. We are happy for the people we love(d) 

She is not a regret, because her time has passed. She is solo yes, but you are not. It is far worse if YOU were solo, and she is not. But perhaps this is what she WANTS: to be solo. So no worries there 

It is ok to think of the good times of the past. But also consider the potential goodER times in the future with your soon to be wife.

Do not hope for her returning. That will mess things up. Hope for a great time with your family. That would be the best, right?
