Reading your sitch, apart from a few minor details...I could have wrote it myself, your's is very simular to mine.
You have got some good sound thoughts & advice already & even though our sitch's are simular I don't think I can add to much to what you have been told here. I will say that you are doing what I have did in the early stages & I say it's the right way forward. Give her the space & don't chase, but also if you can, keep what ever contact you have to your advantage. I guess I mean, if you have buisness to disscuss then use it to shine with confidence & brightness. Like my wife & I, you don't have kids & most see that as a God send in seperations, I agree to most. However, without kids the face to face contact "could" be minimal & I think most would agree that without some sort of contact, you lessen your chances of breaking through to your wife. With that said please don't look for any old reason to call etc. Use what ever valid reasons you do have, and make the most out of them.
The pain & hurt will pass believe me, it will. It's been six months for myself & i'm now at a comfortable stage. You will too, maybe not as soon as you would like, but you will be fine, trust me.
If I can give you any advice that I would say is good advice....That would be to begin by remaining friends with your wife, even though it's hard at times. Try to maintain a friendship but do not make yourslef a doormat. From the start I deciced that I would try to keep all contact cival & friendly & I can tell you that there was not much contact at all. At the moment, contact is semi regular & phone calls have gone form what were a few seconds to a few minutes, not much, but the difference is there & it's important to take note of the little changes in your wife & her attitude towards you. Face to face contact has gone from zero to her been in no hurry to get me out of the door & the last time my wife came here she was here 1.5 hrs. So again look for the little changes along the way.
Be happy with you & it will show. Be friendly, carm & confident in yourself.....It may not win your wife back in an instant or even ever. But one thing, it will not make your sitch any worse. I strongly believe that my sitch has improved & your's will too. Time & patiance or such key factors mate.
