You and I actually started on the boards about the same time. I changed my handle.
Dating after the D is tough. I found someone and thought she was the one about a year after my D started. Turns out, I wasn't the one for her. I found it more crushing than my D. I have had others on here tell me that is not uncommon.
I know I had some walls going into the r after the d and I doubted I could truly love again. But I did love her. More than I did my wife. So it is possible...but the pain can also be twice as deep (at least for me) because of what we learned here and our Ms that ended.
But try and be open and honest from the start. And if you suspect there is tension and you think it just might be a mood, ASK. Don't take things for granted and think they will tell you. After all, we are all only people and 99% act the same way.
