I'm recently divorced man. We terminated the marriage and cancelled our legal duties. I feel so free now!. 
Sorry to hear that, but glad you're feeling good about it.
Yeah, for sure. Divorce laws are different all over the world, but where I am we needed to go to court and through the legal process. But it was totally worth it. 
Was it very costly?
Well yeah, a bit. The lawyer was a lot also. An annulment would probably have been much easier, just declaring our marriage null and void. 
How long before you can annul? I think there's a limit right?
Hmm, I'm not exactly sure. Although when you get one they consider it retroactive. Meaning an annulment makes the whole marriage be considered invalid from the beginning. 
Make it sound so simple. What about kids, did you also have to deal with child care, custody, so on...?
The child custody or legal guardianship is definitely a tough question that I am not experienced enough to answer. We don't have any kids. In that case though the designated parent will have the right to make decisions on behalf of the child.
Oh, that's good. Having children together would have made everything more complicated.
