Head says to disown my family, heart misses them and keeps wanting a relationship w/ them...?

i got married at 20 and now am 26 and have 2 kids. We moved away from my famiily due to all thier problems. my family only consists of my elderly grandma who is great but my uncle embezzled money from the post office and TRASHED my rent house i let him live in for FREE while i was out of state for husband for finish school, and never paid me the money for the damages, I actually caught my blood aunt having an affair w/ my blood uncle () 10 years ago and she is crazy but she is 'nice' and 'fun to be around' but has regularly caused alot of stress in my life, backstabbing and participating in rumors that are far from the trust about me when i didnt even live in the same state, just for enjoyment, and my own mother married an a s s h o l e when i was 14 and i was bacicly on my own after that, my boyfriends family pretty much were my parents at that point. I am just so super nice and stupid and my heart still misses them that i keep giving them chance after chance. My mom calls me on the phone "blah blah i am gonna divorce my stupid husband" and gets me all worked up hoping she will leave him and come stay w/ me in texas, but she never does. I needed some help, had some major medical problems and my own mother wouldnt drive 6 hours to help me and my 2 kids out while i was knocked out on pain pills and asleep all day every day. My husband helps ALOT but has to work to keep food on the table and bills paid. I do have friends here but they work full time. My family has never been there for me when i needed them but im still so damn nieve and forgiving and overly nice, and i take them back and let them hurt me over and over. I recently planned a trip over there to visit them but one thing after another after another has kept me from leaving, plus at night when i try to sleep all the crazy stuff they've done runs thru my mind like 'why are u even going to visit them w/ ur kids, they don't deserve your time'.......i am so confused. i know it sounds cut and dry but w/out them, my life feels so empty. they are 'nice and fun ' to hang out w/ but they are so miserably immature and CRAZY, my own mom doesnt like to baby sit her own grandkids, its too much 'work' for an afternoon wheni come into town to visit so i can go out w/ a friend. I dont know what to do, do i just not look back again?
