You're not the problem , humains are dead , maybe still 1% of humains in earth , i bet you're on of them cause you said "my kids are my world" that meen you love them , and people that can love are few , people only search for other to have love with and after that good bye , they don't want to have kids , they don't want to wrist time like they say , they can have sweet times why wrist it with kids ,they don't understand that their's who realy want to have kids , but it's impossible cause he have a problem and he will never get them , that person is me , you're so lucky with your kids , i wish if i can help you but i'am only 18 , i guess you don't want to marry a kid , lol , but please just don't jump any where without see where are you jumping to , your kids are more important , i know you don't to be alone , but it's better than been with a wrong person ,take care of them
