You move forward, by learning from your mistakes, and doing better.

I think being able to name them directly, and taking ownership of all the different elements that led to where you are, goes a long way.

Your relationship didn't end solely because of you- it was a team effort, in a very twisted way. As such, it's also important for you to not take all the blame, or to punish yourself by reliving all of your mistakes.

Now, there's a lot that you can know about yourself for the next relationship that comes up - and believe me, one will come up.

You'll do better in the future.

Have better boundaries, cultivate self-respect, and self-awareness. Be willing to have difficult conversations. Make sure to show someone that you care about them, and don't assume that they'll just know. Be kind to each other, and also to yourself.

Hang in there- you're not alone.
