Hello C. blanca,
Welcome to our forum.
I can easily understand feeling envious about that new love feeling (which we often call NRE, New Relationship Energy). I'm sure it will get easier over time, and never say never, who can say what the future holds.
There should even be some RRE (Renewed Relationship Energy) bouncing back to you from this new relationship, and hopefully your wife won't let the NRE cloud her mind so much that she forgets to give you the extra reassurance you need. NRE can be a little blinding, so don't be shy about reminding her about your wants/needs (and just a, "Hey, I'm here too," reminder).
Glad you could join us, hope we can be of some help.
Love means never having to say, "Put down that meat cleaver!"
