hey babes,
i could have written your post word for word.
As you know i am much older than you are so please receive this as sisterly advice.
I vented to my mum about DH for about 10 years and she has ALWAYS used it against me. She always tells me to break up with him, end my marriage. Never any good piece advice about our marriage such as "do this or do that" always "you know hes not gonna change" or "i know this marriage is going to end, so just give up trying" etc.. Again, my mum doesn't like him because i eloped.
I have only just awoken to the fact that i have let my mother just a bit tooooo much into my life. I have given her too much power over my life. I stood up to her one week ago, she left and i haven't spoken to her since. It's sad, but do you know how good i feel? I feel friggen awesome. Don't have negativity in my life anymore.

So, i don't want this to happen to you, so please don't vent to her. When you know she is about to say something negative about you, your bubba, your DP, your new "family", you stop her before she opens her mouth. You don't let her say anything bad, because she is instilling bad thoughts/opinions into you and it will affect your relationship in some way now or in the future.

xxoo
