My husband, my 6 month old boy and I used to live in a small city without any other relatives except for my brother in law, who used to visit once or twice a week to keep company with my husband and play videogames or watch a movie. He sometimes eated with us, and also helped and brought some food as well. About a month ago the brother brought his wife from another state to live in a small appartment 5 minutes away from us. I thought it would be nice to have a female counterpart in the family but it has turned out hell. They both show up every weekend on Friday, Saturday and Sunday evening without even calling and expect us to feed them. They sit in the couch of the living room to watch TV and eat our food while my husband and I take care of the baby, clean, take a shower, study, cook, or do what little we can in our little spare time. We can’t even go out anymore. They dont offer to help, or bring any food, or clean after themselves, or invite us to their place. They spend their money in crap like beauty bars, dates, new expensive furniture and clothes, but they want to eat from us and spend our electricity. They are both college students and work 1/2 time. I work full time and my husband works 1/2 time and is on a Master’s program. We have to pay for daycare and are struggling to save every penny. I know it is easy to shut the door on their faces and I am willing to do it as a last resource, but can I have any creative tips since they are "family" and our "only" family in town? I am sick of being nice but I don’t want to create a quarrel unless there is no other way. Thanks!
