Lissie had a H leave her with a few kids. They just got divorced and her X is with OW.
A lady in MLC BrandNewDay had 8 kids and H left for a year woke up and came back. She is not pregnant with #9. She is one tough cookie.
On being alone. It took me two + years to be happy doing things by myself. Being by yourself is a learned behavior and the learning does not come easy or fast.
For you it may take much less time. I was triple whammeyed by returning from a conflict zone to a inposed divorce and given the option to move away from my d13 or retire from my civillian job. No sympathy I made choices to get into that fine mess. However I'd rather eat broken glass than repeat that process again.
Yesterday was the date X and I were Married and I spent it on the Pacific coast looking for whales. Shamu says howdy to his mates down under. Anyway doing things previously was difficult at best unless it involved physical effort and total concentration so I forgot about the situation. Now I don't think about it but that simply took lots of time where the emotional catches up with the intellectual.
You are going through many emotional changes and frankly I do not know the extent but I firmly believe the Left Behind Spouse goes through physical changes. See " Sudden Divorce Syndrom in Men" posted on this forum earlier this month. I believe both sexes can be impacted by the physical ramifications of a breakup.
Willing yourself not to feel blue or trying things as you did does not instantly cure the heartache but it's walking in the right direction. Working out is one of the best things you can do and having men sneak looks as you walk away displaying the results is a plus for the Positive Mental Aditude. Good for you.
