Like I used to do when I first came here, you seem to talk and think a lot about what everyone else is thinking or feeling.
How he is hurting and you don't want to add to it and send him to jail.
How his parents are dealing with their own health problem and you don't want them to ahve to deal with him.
How people will react when you say your engagement is off.
It is time to focus on you.
On how his behavior effects you.
On how you feel.
On what you need.
It is OK to put yourself first.
You wouldn't even need the pregnancy for it to be ok.
You deserve a happy and safe life where you feel loved.
Where you get back as much as you give.
You do not need to justify any of your actions beyond that.
If the reason is simply it is what you need to do to be happy, that is reason enough.
You deserve to be happy.
We all do.
But many of us codependents forget that.
