Besides saying "grats!" the serious answer would be situation dependent. In your original thread I just skimmed, saw you said it was mutual(?), and clapped out loud for you. I've gone through one divorce in my early 20s and it was the most liberating feeling I ever had. Even though it was lonely and slow the first few months, I got back in the swing of things being single again and really started tearing it up and having GREAT time. Seriously, it was awesome, and I raised my standards on who I would date SIGNIFICANTLY. Not necessarily by looks, but more by "how un-stereotypical is she?" My ex-wife was HOT. Like, omg freaking HOT but the amount of crap I dealt with was unbearable. I ended it and realized why people divorce perfect 10s. I had quite a few guys go "WTF?!?!" but a few of the older guys definitely understood. I don't tolerate a woman's bullshit at all any more, and I am engaged to a freaking AWESOME woman now who hates the stereotypical woman type more than I do. Seriously, go out, be single and tear it up bro style until you get it out of your system. Then don't settle emotionally until you meet a chick who's on the same level long term as you and doesn't tolerate the same things you don't tolerate. It goes more in depth than that, but be honest with yourself with the dumb shit you did to piss her off also, but damn sure don't tolerate those same things again in the future.
OH! Also, stop being a fatty. No seriously, I'm not trying to dig on you dude, but hit the weights like your life depended on it, watch your damn diet, and get some cardio in. Obviously just calorie restrict for the time being while still getting the protein you need, and once you get close to the 12% range start trying a cyclo-ketogenic diet. It takes a lot of work but holy crap does it pay off.
I have no clue how your training goes but don't do the dumb shit of doing cardio before weights. Weights then cardio.
