My sister is a spoiled brat and a little too close to my husband for comfort.

My sister is 21, my age 29 and my husband is 31. She was an oops baby. We were an oops too but not as unexpected as her. I like to call her the gift of an IUD. <br><br>My sister has been a difficult child from the beginning. She has major back issues, sclerosing bone dysplasia and a small penis looking growth on her sacrum. I heard a lot of stories that while she was a baby she would just scream for hours. My mom was exhausted and depressed. I was put in charge of my sister a lot, I took care of her, did her schoolwork with her, fed her, bathed her, took her outside to play (I do not mind that part), took her to all the appointments and surgeries, she has been through 8 surgical procedures, countless hours of PT, OT and now speech therapy. Even from a young age my parents encouraged her to talk about any issues she has with her back. My mom would literally ask her to touch her front hole and butt hole and name the anatomy. I was uncomfortable with it. <br><br>At times I wanted nothing to do with my sister but then she would hug me out of the blue and tell me she loves me. When she was a toddler my mom got a job nights 2 days/week and I had to stay up with her to make sure she slept through the night. I was 6 at the time. <br><br>She had an IEP until middle school and got into the 2nd track for HS. My parents wanted her to go to college but after failing her first semester, they insisted she work instead. She has had 2 jobs and been fired from both. She currently does odd jobs and spends most of her time taking walks in the woods and taking pictures. I do not believe in letting a kid just be lazy because they have a disability. <br><br>When I got married I asked my sister to be the maid of honor. She spent the entire reception socializing with my husband's friends instead of making sure I had what I needed. I didn't mind too much though because she seemed to be having so much fun. <br><br>When I was 5 months pregnant with my son, my sister was evicted and my husband and I took her in. I was a stay at home mom, I didn't work at all. We had a 3 bedroom house and live in a red state. I was so grateful to be able to stay at home and take care of my son. Our house was nice but not too large. The backyard was entirely fenced in. My sister got my old car, and some of my old clothes. I gave her a budget to buy new clothes and fix the car. I did not charge her rent but expected her to help out around the house. I did all the cooking and cleaning. She did not help with my son. <br><br>My son got whooping cough at 3 months and had to be isolated. My husband took time off of work and my sister offered to help with my son but my husband and I declined. I was so grateful to have my husband be able to stay home with my son. When my son got sick my sister started going out a lot more. Sometimes she would take my car and leave without a word. She had a lot of male friends and they'd come over to hang out. I did not care too much until her friends started bringing over alcohol and staying late into the night. I'd tell her to quiet down and then the noise would get louder. <br><br>I'd see my sister touch my husband's arm a lot when she talked to him. She'd hug him and kiss him on the cheek. I'd see him look at her and smile. My sister would do whatever she wanted and my husband would let her. He'd let her borrow my car overnight, drink my wine, come home whenever she wanted to. I'd tell her it's time to be quiet because my son was sleeping and she'd stay in the living room howling with laughter with her boyfriend. She'd bring men she'd just met from the bar over to the house and my husband would allow it. I'd ask her not to but she'd say she was a grown woman. <br><br>I started noticing my husband stare at my sister. I'd catch him looking at her cleavage. He'd stare at her ass. I felt like something was off about our whole situation but did not know what to do. <br><br>My mom said to just let my sister go, but I was sucked into being a mom to her. I did not want to let my sister go because I was afraid of how my mom would react. I felt like I had to take care of my sister her whole life. <br><br>One day my husband and I took my son out for a walk. It was a winter night but we were all dressed warm. My sister stayed home but my husband did not lock the door. When we got back, my sister was in my bed with some guy. They were both naked. My husband got angry and said that wasn't okay and my sister got angry back. I stayed quiet. My husband said to my sister that she's got to go. <br><br>My sister moved in with my mom in March. It's been a huge relief to have her out. We did not tell my mom what happened. We told her my sister was too messy and obnoxious. I'm not really sure where to go from here. I do not trust my husband. I do not like thinking he was having an emotional affair with my sister. I do not want to talk to my mom about it. I do not want to kick my husband out because of the economy. I want to move but cannot with the way the housing market is. I do not want my husband to help me with my son because I'm worried he'll leave him behind like he did me. <br><br>My mom said my sister would die without me. That isn't true. My sister has tons of friends and dates multiple men. I wish I'd never had to take care of her. I wish I could have been a kid. I feel like my whole life I was taking care of my sister and taking care of my mom by taking care of my sister.
