Hello, I  have a very big issue with the family situation of my bf. I am at the stage of considering leaving it all. So,  he is fighting with his wife for the child. The circumstances are unusual. When they found out he had  fertility issues,  she demanded to resort to sperm donor fertilisation. She didn't give him much choice: either he agrees or a divorce. He was so desperate to save this marriage and make her happy, so he agreed.IT WAS A HUGE MISTAKE.  After 3 weeks from the procedure, she told him she no longer loves him and wanted divorce anyway. The next day she found out she was pregnant. He tried to convince her to try to fix the things,  but to no avail. SHE left after 4 months and for a another Man ! He tried to be amicable but she become aggressive. She wants nothing to do with him,  saying that is not his child anyways. Since she has been living with this other man , my bf tried to get out of this arrangement that  he no longer felt obligation towards.  She initially said yes,  but thanks to some lawyers, she delayed changing the paperwork until it was to late( after the birth is to late).She doesn't want him to see the child saying is not his. Now She has a second child with this other man  who basically is the father to both kids. My bf has been reduced to being a sponsor. He pays very high child support and the lawyer bills. This is going on for 3 years and all he has got is 3 h every 2 weeks with a Supervision. He is treated like a criminal.. although he is the most gentel  man I know. He had to go to psychological testing, which his wife demanded just to delay the ruling. The child doesn't really recognize him as a dad, which given the little time they spend , is normal.  The other guy has all the parental privileges and gets to be called dad. There is no way they can bond in this circumstances. They cannot even divorce as there is no agreement between them about the child, so for the foreseeable future we cant advance as a couple. Apparently she knew this guy from the university times, as no man would accept pregnant lady easily. Maybe they had planned it all. It's an impasse. The only solution is to either fight further for alternate custody, so the child could properly bond with his legal father, and so my bf could  finally get to be real dad on daily basis. Other alternative is to propose to her partner to officially adopt the child,  as he parents  him on daily basis since he was born. I am not sure if any of these options would work. We re really exhausted of this battle. My bf tries to distance himself from  showing no emotion or covering them up with other stuff,  like shopping. We feel that the child should have  1 father,  either my bf or the other guy  but not continuing this weird arrangement. Actually,  the boy has also a bio dad ( sperm donor) that he can learn about when he turns 18. He doesn't need 3 fathers! The thing is, if it continues as it is,  I can not stand it emotionally  and psychologically. It is draining,  and seeing how much money he has to pay and gets nothing out of it , is very upsetting.  I struggle financially. need to watch my budget  and all this monthy expenditure seems so unfair. His wife comes from a rich family,  that  owns several possessions, so this money is not even needed. I would appreciate any outlook. I don't want to get myself into overtly complicated situation that doesn't seem to have a solution. I have a lot at stake,  he nothing to lose anymore. On the other hand,  he is a very good man,  maybe too good,  and that what got him into trouble.
