Am I wrong to be pissed? Long story short we into hard times financially right after finding out we were pregnant lost are home and had to leave everything behind as we had no where to store let alone get it to storage. We got so low we slept in our are for a couple weeks. Now we are at his parents planing to move out in feb only 4 weeks before little man is due. They said we must help out which of course we do but it's starting to look like they only wanted us here for our money. The mom can't work as she has cancer the dad is a felon and lazy as fuck and waits for a mowing gig to come along, the 23 year old brother is a addict and same story as the dad and my husbands twin sister is lazy and into her phone 24/7 so much that her 5 year old doesn't know his colors can't count let alone know the damn alphabet when there's nothing mentally wrong with him! We have a car that is a damn gas hog and drive it everyday to work if it's not to work then is 25 mins away to the hubs grandmas to drop his sister off at just so she can stay there for 3-5 just to watch the walking dead everyday and eat all the food there with her son. Or to take his dad to get fucking weed 3 times a weeks before putting food in his family's bellies or paying the bills or to take them to the methodone clinic which leads to why I'm pissed now because no joke we are putting $100 in has a week and the mother just came up to my husband and said when we get paid Friday they need money for bills and food and that it's bull shit that we have only giving them $40 for a water bill which didnt even get paid we found out but was instead spent on weed! I'm sorry but fuck that and hell no!! If $40 is the only thing they see with helping them out and not running them around everywhere and buying them food some nights because they don't want to get really jobs to take care of themselves then I'm done helping. I'd rather go back to sleeping in my car then deal with this shit. I didn't even want to come here in the first place and be around these people. The 5 year old makes you want to slap the shit out of him so hard because he gets on your nerves THAT bad. The addict brother and lazy father just sit on their ass and watch movies all day and the sister who is so obsessed with her phone and drama that she just walked in the rain to pay her bill yet here I am working 40+ hours a week at a job where I have to run around all day at 25 weeks pregnant and I'm to just hand over my money knowing it's going to go to weed and shit. They just smoke at least $100 worth of weed in 3 days but I have to pay their bills and feed them?! 😡😡😡😡
