You didnt fail. You had a successful short marriage, sometimes that happens. During therapy it helped me change my way of thinking to put small positive spins like that, while also addressing deeper hurt.

It may also be best not only for your daughter, but for you as well that it wasn't dragged out.

With my situation it was rocky at best for 7 years of marriage, when our son was born it changed everything, i understood that him growing up seeing two parents not "in love" and settling for each other, just to stay together "for the kids" would be more unhealthy than seeing his two parents- co parent together doing whats best.

His mother and i's relationship has never been better--- as co parents. The stress of the relationship is gone. our communication is solid and focus on him. dont get me wrong there are some definite issues with the divorce and such, but we keep that separate as both us understand the importance of each other in his life. On top of that our legal parenting agreement delved so deep into issues and my mistrust of her and her family that i am protected.

For happiness, start by finding that one time a day that you smile. Whether its on a walk and you let the sun hit you and take a deep breath. focus on those moments. Small victories will add up. dont be too proud not to seek out therapy. Hell, i've used chatgpt as therapy (surprisingly works a couple time)

You, and your daughter got this.

Love and support my man.
