The 'Arrested Development' star, who split from the 'Parks and Recreation' actress last September after nine years of marriage and shares custody of their two sons, Archie, four, and Abel, two, admits he initially found it difficult to move on but he is happy with his life now.
The 43-year-old actor told Details magazine: "If going to the gym obsessively for eight, nine months was my way of dealing, then let that be my worst problem. Life is challenging, and I'd say that there's no guidebook -- but there's about a million guidebooks out there. All people have been doing since the dawn of time is trying to figure out how to live this life and be happy. I'm no different.
"I'm 43, and I've found my happiness - which is my kids."
Will, who was also married to 'The Artist' actress Penelope Ann Miller for a year until 1995, insists he still believes in love but isn't ready to start dating again.
He said: "Certainly. I do. I do. I'm not officially dating. I don't know what you do. Do you put out an announcement in the trades? I'M DATING! It all seems very scary to me, to be honest. So I'm kind of keeping pretty close counsel right now."
