And just why would we do that!!! You do sound incredibly defensive SS, remember that we are only responding to your posts and what you say in them, we have no idea about your wife or how she feels.
But then saying that it's hard not to get so defensive isn't it? I hope you don't read this post the wrong way, but this situation reminds me of my sister. She phones me up to complain that her kids are misbehaved, that she and her dh never have an evening together, that she is massively in debt, that our mum never lifts a finger to help her, that she has no friends, etc, etc. I give her advice, I make practical suggestions to her, I try to help the best I can, but she makes excuses as to why she can't try this or that, how she's done this and it hasn't worked so she won't do it again, how I can't possibly understand her situation, etc. For me it is extremely frustrating.
Reading back through this thread there are so many suggestions, so much advice, but you seem scared to act upon them. You say that you want to hear from someone in a similar situation. Well that's not possible because your situation is unique to you, and whilst we can all sympathise with bits of what is happening to you, we can't possibly understand everything that is going on in your life.
Whenver someone comes up with a good suggestion, you seem to be saying, "yes but.....". Why is there a but? The only person who can change anything is you and your wife. You cannot be her friend and lover if you do not communicate with her. How can she possibly love someone who she only sees for 2 hours a day, and who is unwilling to take on some of her burdens? And I don't mean household burdens, I mean mental burdens.
You speak eloquently of your love for your wife, but they are only words to her, she needs actions. My dh could tell me he loved me till the cows come home, but his words mean less to me than gestures. I know he loves me when he puts down his newspaper and spends time just talking to me. When he comes in and notices how tired I look and offers to cook tea for me. When he arranges to take my dd off my hands for a couple of hours at the weekend. When he buys me a chocolate bar just because. Ok, you may be frightened to take the bull by the horns and you may be pushed for time and you may not have a lot of money to spend. But that doesn't stop you from taking 1/2 out to ask her about her day. Or to bring her some choccies home. How much is a bottle of wine? How much is a video to rent?
I understand that none of this is really what you want to hear, but I don't think any of us can provide you with any of the answers you are looking for. We cannot say if you wife loves you or not, if she's having an affair or not. All we can do is to offer advice and say how we would feel in that situation. I'm sorry if this makes you feel a bit 'got at', I can understand that. But I honestly believe that the ball is purely in your court and there is nothing more we can do to help. However reading these, you have a lot of peoples best wishes and we are all rooting for you. Take strength then from our support!
