Hello mom, I need a real piece of advice and a different perspective. We broke up before our daughter was born, after she was born I wrote to him that I had given birth to a daughter. I informed him. He didn't show up at the hospital, it turned out he already got married again. When our daughter turned seven months old, he came to the registry office and gave his surname. Then we took a picture together as a memory. He disappeared later. He came to his daughter 3-4 times during all that time and that was it. I want my daughter to have normal relationships, I want her to know about her father. It's important. It doesn't matter what happened between us, why should children suffer. Only when I write, he comes. Otherwise, he comes on his own accord - no. What kind of irresponsible father is this?! He pays pathetic alimony of 15 thousand TGS. He specifically told the judge that his lowest salary was the reason for this. Fine, whatever. But why doesn't he want to see his daughter? Or is he doing it on purpose? I still haven't figured out what the problem is. She once asked him why he always gives excuses, saying things like "work," "you live far away," blah blah. The worst thing is that he didn't congratulate his daughter on her birthday. Although he knew perfectly well. I invited her to the party. Strictly formally. But alas, he remained as stupid as ever. He has a son, who is one year old. Soon, I will give my daughter to kindergarten. We need money. I want him to support her. He always comes with empty hands every time. There's nothing to buy for my daughter. He doesn't even think about it. I was very patient with him because of my daughter. But my patience is running out. God sees, I never forbade him from seeing his daughter. What should I do? Write him? Or send him to all four sides?
