When I was so down I was extremely vulnerable and my Mother is extremely manipulative. My mother told me that H had touched the girls inappropriately. Now I NEVER believed it but it was one more thing incouldnt cope with. My mother set into motion terrible dealings and I refused to follow through with any of it because i didn't believe it but still had to do various things cos the complaint had been made.
When I rAn I ran to their place first and therein lies the betrayal. I know now I should never have gone there but I was lost and confused. I lasted a few weeks and then fled from there as well.
Doesn't sound like a "betrayal" to me; it simply sounds like your mother was trying to break down the marriage at that time...and she almost succeeded, because SHE was the one who couldn't let go of YOU.
I left my family of origin behind, and did what I was supposed to do, but my husband was the one who didn't make the break with his mother/family...and his mother was extremely manipulative and controlling; telling my husband I was having an affair when I wasn't, and a whole host of other things to try and break up our marriage. It didn't work; but the issue of making that kind of break came up in his MLC; interestingly enough, during his MLC affair.
Running home to mother because of manipulation and control; is something that has to be broken within one's self, as when one marries they must "break" the ties that bind and strangle; and parents who won't let go of their adult children need to grow up themselves.
You DIDN'T betray your husband in these actions; your mother took advantage of your weakness and vulnerability; and she will account for these actions when the time comes.
You may see it as betrayal; but I see is someone who was unable at that time to break the hold of someone who was controlling and manipulating...and one who couldn't let go of you; that was VERY disrespectful of your mother toward YOU as an adult.
Stop blaming yourself for the web your mother was weaving of deceit, lies, control and manipulation.
You are still blaming yourself; but as you grow through all of this; you will see that although you had your part in this; your "conditioning" was the fault of your mother...as it was all you knew at that time.
As you learn another way of dealing; the guilt you have will dissolve away; and the child you were will become an adult; if that makes sense.
I had to deal with being controlled and manipulated, by my parents AND my husband. I made my stands when it came to my married life, resulting in my dad refusing to speak to me; and that lasted until his death in 1994...Dad couldn't control me so he refused to have anything to do with me to "punish" me for my "behavior" toward him.
Yet my husband's control of me was dealt with during his MLC...and my husband accepted my boundaries, whereas my dad did not accept, and chose to walk away from a relationship with me.
This was NOT a betrayal of any sort; it was me standing up for what I believed in.
Anyway, plenty of food for thought; cut through your guilt, and see the situation for what it really was; changing what you can, and letting the rest go, last of all, forgiving yourself for being human; picking yourself up out of the dust, dusting yourself off, and go ON; leaving this all behind.
You cannot change the past, only the present, and make the future a better one.
I hope this helps you.
