I also realize there are solutions here, it is more the overwhelming amount of people going through these tough times. I do better just not obsessing over the site all day and moving to something else to occupy my mind
I get that. Staying busy is good.
EA or PA it makes no difference, she will not respond in ways you will understand for a while while her brain is awash in love chemicals. She "feels" all gooey and it isn't for you if she is having anykind of affair.
Are the over abundance of txts to the same person? Time of day?
Next time she feels all amorous you tell her, "Let's stop I don't want to give you the wrong impression." No more back rubs or cuddling while you are "deciding" what to do. You need to find out if she is out of bounds with the texting, if she is then the first thing you need to decide how to put a stop to it. This is very hard to do at first but you will get thru it a better man. I didn't totally believe the concepts here at first but the are proven to work. You can handle it.
Cheers
