Agree with Kat, you can be loving, but you need to tone it down.
Your wife is cheating on you. I know it doesn't seem as bad as a physical affair, but when you start declaring your love for some other guy...it's cheating. So, do you want to just be her roomie until she's established the relationship enough to move out? Some on here would say ignore it, it's just a symptom. Personally, I'd choose to say you won't accept it. Either end it with him or find somewhere else to be. Not harshly, just reasonably. And then start focusing on being the best you can be, but not for her, for yourself.
She won't respect you, or even consider the implications of losing you, unless she knows that you are prepared to move forward without her, if necessary.
You cannot be lonely if you like the person you're alone with. Dr. Wayne Dyer
