I think my parents destructive relationship is causing commitment issues to myself?

It’s meaningless to attempt to fill that void with women you don’t care about. Find a different way to fill that void, find a passion, find a friend, but meaningless relationships will not, and will never fill such voids and in turn, will create a new void for you to fill. I do not think you are ready for a relationship at all. As well, I do think that when you do find the right woman, you will slowly be able to get yourself to let your guard down, but you have not been able to find that woman yet maybe because you have not met her or maybe because you hurt her cheating. Either way, you need to stop treating people and women this way. It will not fill your void and it will not make you feel better. In turn, figure yourself out, go talk to someone, throw yourself into something that gives you fulfillment.

We watch and we learn. Be it good behavior or bad, it catches on to us. If you’re exposed to it on a frequent basis you are more likely to act out in the same way.This however doesn’t mean that you absolutely have no say in choosing the way you’re going to behave when you’re in a relationship, but it does have a big influence. Some people carry that on into their relationships while others work on building one that’s nothing like the one they’ve been around. So it’s up to you.

If you don’t like it, change it. If you can, don’t be around it at all. And when you’re ready to join someone in a relationship, keep in mind that they’re not there to ‘fix’ you. They’re not there to deal with your insecurities or your selfishness. They’re not there to be blamed on for everything that’s going dark in your life. No. You have to do that within yourself. Only you can fill that void. No one else.

They’re there to bring out the best in you. To add on to your life, in a positive way. Not to grind you down to the ground or have you do that to them. Nope. And if that’s what you are experiencing then… it might be time to get the heck out of there. Because we are meant to enrich each other’s lives. Not tear them down.
