With reference to an abusive boyfriend I was with in my early 20's:
-wear what I like
-talk/have conversations with people (without being publicly ridiculed)....I developed a stammer because of him (it's gone now).
-not be too scared/feel too stupid/worthless to go for jobs that I wanted to do/was qualified to do.
-not be on edge/scared about how he'd be each hour/day.
-see my friends/family when I like.
-study what I like.
With reference to my STBXH (with him 10yrs: after an RTA, he became an alcoholic/drug addict* and I had to deal with 6yrs of that):
-I can go to work and not worry about whether he'll be drunk/high, or whether he'll disappear for days on end.
-I don't have to worry what mood he'll be in.
-I can go to bed at night and not worry about whether I'll wake up and he'd be gone.
-I can actually sleep properly now.
-no worries about going to work as I managed to change my hours to fit around childcare.
-no worries about my not being able to go into work because he's disappeared/isn't sober or straight and I need to sort childcare.
-no worries about the place being trashed while I'm out working (because he was drunk).
-not being scared anymore (he was terrifying when he was drunk/high).
-my children not being scared anymore.
-I can make plans!!! Like have friends over, take the kids out, have the kids' friends over...and not worry about what state he'll be in (or what state my home would be in!).
-I won't find hidden (empty!) bottles of spirits in random places.
-no need to special him anymore (suicide attempts when drunk/high, episodes of psychosis due to alcohol/drugs).
-no worries about being verbally abused, and (once) shoved/pushed about.
-no more of him gaslighting me.
-I don't have to worry about money/pricey items going missing.
*1st NB....I knew about the alcohol issues and was doing everything to try and help him stop (including getting SS in, rehab, AA, CGL etc etc etc)....I found out about the drugs right at the end of us being together. After 6yrs of trying everything to support him in getting sober etc, I realised that there was nothing that I could do, and it was completely down to him: if he doesn't truly recognise that he has a problem and wants to sort it, there's naff all I (or anyone else!) can do.
2nd NB...to anyone in either the above situations....follow your gut instinct, talk to friends/family/people you trust (don't hide it, you've nothing to be ashamed of), get support and help for yourself/family. And run.
