There is nothing wrong with seeing your ex or running into them. We are all humans, and it is always better that you forgive each other because of the mistakes that you have made in the past. There is nothing wrong with that too. Granted, it definitely does take courage, but that is how it is supposed to be. If you are seeing your ex around town, then you don’t have to worry about anything. However, some people can end up making mistakes in the process because after all, making mistakes is part of being human and that is what we have to keep in mind.
I would suggest that you should never really approach them in hostility. Even if things have gone terrifyingly wrong. It would be better if you are just being responsible and that way, things are going to work for you in a much, much better way. It is better that you act civil and do not let things get out of hand because that would leave a much better impression overall and you will not have any problems, either.
I say this because I have seen so many people being vindictive and trying to ruin things for the other person. This is never really something that you should be doing because it can only make more issues come forward and we have to avoid them in the best possible way. Otherwise, things can easily go wrong and we can end up causing issues that we should not be doing, in the first place.
Rest assured, the more you think about this, the better it is going to be for you in general.
