Will try to shorten things as much as possible....my mom kicked out my 18 & 19 sister and brother in January (no real social skills sister has about an 8th grade education and brother about 6th) so I took them in with only a few conditions 1. do not lie to me 2. get your GED (college is their choice of course it is encouraged but not required) 3. for my sister who my mother set up a man who is 16 years her senior at the age of 16 ( I know this is wrong on soooo many levels but it is not what I am worried about right now) must break up with him to live with me....she needs to focus on her GED and deciding what she wants to do with her life now that she actually has a chance at one and staying tied to this man will influence her decision to an unfair advantage (there are so many more reasons as well and so much more I would love to just unleash about the entire situation, but again not the focus) other than that we told them they are adults live life. A month or so ago I had a feeling she was lying to me and was still seeing him, so DH and I sat her down and said at this point we just want the truth, we do not want to get blindsided by anything please be honest, she still denied seeing him romantically. They have gotten jobs and we have gotten them a phone on our plan, my sister's phone broke, she used our kids emergency prepaid phone for a week,then gave it back to us, with everything still in it....yeah she has been lying the whole time even had her friends lying to me etc (which I know is mostly normal teenage stuff).....so I want to give her a second chance and let her stay with me still, but now I have lost all trust and faith in her and there has to be some rules... this is my struggle, where do I draw that line as she is an adult but she is more like a child not to mention no matter her age she is living under my roof and broke the only rule that was set out repeatedly for months? Being that she is so far behind because of my mom should I treat her like a teenager? Any advice or ideas would be greatly appreciated, DH and I are just at a loss in the situation.
