Ok im really sorry for you situation but come on! You are a grown up woman and you should take the wheels of you life! Your sister has you other 3 kids??? If you cant take care of any kids (financially) do not have kids, i know you and your husband have no jobs and the only thing you can think about doing is having sex but commooon you are not bunnies who copulate all the time and have babies like they were poop. Take care of you life, realize what your doing.
If you have no job, no house or anything like that, do not have a child and dont even think about having sex, think about the job you need to get, the house you need to buy, the life you need to rearreange. For gods sake, it upsets me so much that people cant take responsability for their own actions. Your sister shouldnt be having to take care of your kids, you should be doing it. Havent you heard about condoms, pills, pull out etc etc etc? theres even an operation that makes you unfertile! And i think its actually free!
This is a 16 year old teelling you to take control. Your husband should get a job, if he does not..leave him. You should sorround yourself with people who gives you something (spiritually, mentally, material etc) not taking away things from you (energy, time, money etc etc ) and that man is taking things away from you.
You should get a job aswell (the two of you should have like 3 jobs each) you have to be creative and i dont know, start a business (with the money from your jobs), sell some stuff from your "house" for extra money. Use that money to buy a house, pay the education for your kids, built a future for your family, show some respect and appreciation to your sister. Get over yourself.
Stop writing on yahoo answers and do something. Make a financial plan. Put things in order. Remake your life. You are a perfectly capable strong woman who can do whatever you propouse to yourself. Make a change. If you are capable of ruin your life the way you have done, you are capable of put things back in order.
Im sorry for your parents, but change things to make them proud. Be responsable for the 3 kids, and 4 soon, that you created...not to live with their godmother, but to live with their mother in a perfectly nice house (without it being fancy or anything) having perfectly nice education, and being able to make a future successful life for themselves, and they should be able to say in some not so far future "thanks mom, this is for you".
Wanna hear those words? DO SOMETHING!!!!
Grow up and stop complaining
