Hey L, I also New here don't have much guidance but one thing I know every W or H that magically wake up saying ILYBNILWY has met someone weather is emotional or physical they are now in LOVE with the love of there life. The question is do you really need to know if W is having an affair. Sometimes things are better not knowing if you want to work on your marriage.
As far going up to meet an Ex hmmmmm my opinion is you should reconsider I know she tells you she not interested in relationship but that's what they say, do you really wanna bring up old feelings and hurt her in this process or even yourself. If you looking for some fun then do a one night stand but not someone who has had a rough life as she told you. I know that we all LBS want to feel wanted and needed I know but I also have thought about the other person am involving no matter what we are humans with needs but also with emotions. I know I put myself back to the day W said ILYBNILWY I tell myself I never could make someone feel that pain it was to painful. But you know what's best for you to heal. Just take it a day at a time and you will find your peace to your NEW beginning.
