It's easy to come out of JWland having bouts of self-doubt and feeling unlovable or rather un-deserving of love hence the unsuitable partners, deep down you think you don't deserve any better. So pretty normal response to being a part of a high-control group for any length of time.
I think being a JW and being around JWs can induce a feeling of being helpless victim. I know with myself I am making great progress in my healing and undoing all the JW thinking etc etc and then bam if I run into a JW and have a conversation I have a minor setback for few hours or so.
I see it now as being a normal part of the healing process and remind myself that only a couple of years ago running into a JW would have set me back weeks not hours so I have come along way. But, it takes time and sometimes you have got to learn how to love yourself. Difficult, as loving one's self is a sin in WT land but a healthy measure of self-love and self-care is vital for mental and emotional health.
Basically you have to learn to love yourself enough to treat yourself better.
