You certainly didn't misjudge your unhappiness with HIM.
Bucyn thanks for this !!
When you see them and they look great it is also easy for self doubt to come again. My XABF got someone else right away (in fact they flirted while I was still with him, on the same outing, ughhhhh!) and it seems rather serious... and I think he may be a good person, yadda but then I overhear him talking about beers or bars and people say he has arrived still drunk to work .. at 9 am... and I know the only problem he had with me, was that I would not drink with him alcoholically...
Let me look for an anger mgmt thread because there are great tips to get that anger outside!!! it is a natural feeling and it helps you to move forward faster..... I prefer to be angry than sad .......
Hugs!!
