To the original question about getting into abusive relationships and how to break the pattern. Essentially, first you have to make some real long lasting changes to your own life before you can expect the quality of your relationships to improve.....I believe we attract what we are.......unwell begets unwell.....
Here's my list.
1) You have to make significant changes in the following ways:
a) evaluate your social contacts for their addictive behaviors, emotional maturity, integrity, trustworthiness, confidence, and follow-through (if they don't walk their talk....dump them). This was the hardest thing I did.....but the most mentally healthy step I took....including family members.......
b) Then evaluate your own addictions, integrity, honor, values like honesty, tenacity, consistency, dependability, respectfulness, a desire to change and motivation to do so, and make a plan and write it down of the things you will change-and how. Daily work on the things that will help you develop healthy relationships (addictions, self-care -like bathing and grooming.)
c) Seek out and expect higher caliber/more emotionally mature friends and relationships (because higher caliber friends tend to draw more emotionally mature friends), who aren't all caught up in a divorce, a waxing/waning relationship, drama, and who are positive thinkers.
d) get some hobbies which require music, art, or thinking and fun and do them in groups or clubs......to have something in common to get together again and again......then you have something to talk about, and you can open the door to even more learning.
e) become friends first, and for a long while....it's a whole lot less complicated.....and likely to be easier to get out of if you decide that it's not working for you....
f) if you want to have friendships, you have to actively contribute.....bring your potluck, be on time (a huge indicator of emotional maturity and groundedness), and don't frustrate potential friends using a wide variety of excuses, ailments, etc. Show up.....unless you are contagious.....even if for only a short period of time to deliver the potluck and then go home.
f) Relationships have a balance of give and take: consider giving to someone something each day....whether a neighbor a plate of cookies, a kind or motivating word, fixing an old ladies toilet, giving someone a ride, or helping them pack up to move. I find giving.....helps to insure I'm not a burden on someone and primarily a "taker" and the relationship has a built in give and take....
in the relationship. This is critical for longevity.......when people see and feel you care....they care back.
g) Always walk your talk, and you have to be emotionally healthy to carry through (if you are drinking regularly or self-medicating, chances are you'll attract the same-drama-and ill-health)
h) Take care of yourself physically.....so you can do all the other things listed above.
i) Read, find out what is interesting and fun in the world....and read about it.....develop interests in what is going on around you.....this helps you get a life......PTSD can squelch your "knowledge" .......read about every question you have and know some arguments for both sides
i) Now, I evaluate initial relationships....did we click, was that person's views aligned with mine, was he/she interesting and up to date on current events, did that person make me feel comfortable, did I like or not like them (and note why or why not).....I'm not over-analyzing or anything....just keep tabs on how I feel-from a gut perspective....and if I have any nagging concerns, address them immediately with myself......I don't toss red flags in the invisible box anymore and put the lid on and forget them.
Now, after trying this on for 6 months, look around and if you see needy people, hanging on, showing up and asking for things....set clear boundaries and roles for relationships...... don't encourage folks who are dramatic, needy, or don't follow thru on what they say (red flags).......drama perpetuates drama.....and drama comes from lots of immaturity.
Honestly, I had to get out of the dysfunctional "needy role, " have a daily schedule, have something to contribute to a group, before I could attract more emotionally mature friends. I speak from experience......I now have healthy friendships and healthier family relationships than before.....and I've pulled back from less healthy relationships and don't give them near the amount of time or attention....they usually go by the wayside.....or become more like an acquaintance....without creating drama to do so......let them go....when it doesn't feel comfortable...or a good fit. People are like shoes.....you got to try them on....and sometimes they just aren't a good fit.....so they go on the shelf....when they are uncomfortable. ;)
