Sorry to hear all this Ajay.
You are doing it right regardless of how it pans out and, really, regardless of whether you hope to reconcile. Quite simply the only thing you can do if he is not breaking off the affair is separating and focusing on your own wellbeing. There's some chance he will come crawling back one day, and if he does it will be entirely up to you whether to be receptive to that at all. Alternatively he may never come back. Either way you gain nothing by pursuing him. In the meantime we are all adults so we try to be civil when there's some need for the two of you to be in contact. I will only say that if he does come back cap in hand, be aware that there's a "be careful what you wish for" element to reconciliation. It is honestly hard to say whether it's better to have back a relationship that is horribly damaged, or to simply be free to spend time with any of the seven and a half billion people on earth who haven't lied to you and betrayed you. For what it is worth, this idea that they were terribly unhappy and it was all your fault is something that people who are having affairs often create retrospectively. I mean no doubt we have all had our ups and downs but what they sometimes do, to justify their behaviour, is revise the past to make it all worse than it actually was. There will be all these things that make sense as reasons in their little bubble, that don't really stand up to scrutiny. For example, my wife has often made a big deal about how I rode roughshod over her preferences to choose the house we lived in for 10 years and had our children in. That it was nothing like what she wanted. This was one of the largest factors in explaining why she was so unhappy that she had an affair. There may be some grain of truth in this as there was some market pressure and I moved the purchase along, but we both celebrated the night our offer was accepted etc. And lived there since 2006. And now we have moved, as a part of dealing with the affair aftermath, and she keeps saying how bittersweet it is to leave the house and how much she misses it. It is actually quite painful to hear, especially since I did so much work on it with my own hands, virtually rebuilding every single room (and it's a big house) and making a really productive garden. That is a bit specific to me - sorry - but you get the point. Some little grain of truth about a grievance can get polished and zoomed in on until it looks like a giant boulder that justified the affair behaviour, the deception, the using you, the whole lot. They have to rationalise it somehow, because let's face it everyone knows off the bat that having an affair and deceiving those who trust you most is obviously wrong. I honestly think the best thing to do in your circumstances is assume he is not coming back and conduct yourself accordingly. If he does come back that's a surprise to deal with (and whether it is really a gladdening surprise or not is going to be very hard to say). If he does not come back you've already been cracking on with making a fresh start for a while when you become sure about it. I admire you for kicking him out when he wouldn't quit the affair, anyway. It's the right call and nobody should put up with that kind of sh!t. Good luck. Others here (like Anna26) will be able to give you much better advice than I can.
Maybe it is okay, maybe it will be okay.
