So my title is the problem in short, one year ago my boyfriend, since 7 years, had an affair for 5 months with a girl , much younger than him, I found out because I got suspicious because suddenly he always was too tired to have sex with me, even just once a month was not happening, while we were trying to conceive... so then one day my intuition said; check his bag, and I found a long love letter, from a her to him, talking about love, the last phrases were saying that; " there is nothing wrong with telling someone you love them, but that sometimes people are too shy to tell them like wise " ...

I confronted him with the letter and then he did admit that he was having an affair and he said he had feelings for this girl, but never told her he loved her and that what was written in the letter was all a "citation" from a book and that because she is so much younger then him, he was never thinking of leaving me for her. He said that it had happened because he was very stressed, under a lot of pressure, felt not understood by me and was not happy with our sex life, which for me was quite a surprise because I had asked him for months, what was going on, why he didn't feel like having sex anymore and he always replied that he was under a lot of stress at work and just very tired ...

He asked me to forgive him, he didn't want to break up and he did want to build a family with me, so I stayed, I told myself that I would give it some months to understand how I felt and what to do, I am 38 years old ( he is 45 ) and we were looking for a bigger house to buy and trying to make a baby, it was a serious relationship that I didn't want to give up, so now we are almost 1 year further, a very difficult year for me, he is a doctor and works 12 hours a day , this last year he has worked 14 hours a day, included Sundays, so instead of working on our private life, he gave all his energy and more time to his work..

He has not taken any initiative to pick up our sex life, he said that while having his affair, he understood that he was missing things, that what he needs in our relationship, is me taking initiatives to have sex, though when he comes home he always says he is too tired to talk , just wants to eat and sleep, when I only put a hand on his lab, he pulls away or finds a reason to stand up and go to his phone or toilet or needs to check his agenda ... , so I tried to be understanding that he is tired and stressed and not putting more pressure on him, but then he says I don't take initiatives ... and after learning about the affair, I also think , that it is him that should show me that he wants me ..

To make the story complete, a while before finding out about his affair, I also found viagra pills in his wallet, ( which started my suspicion ), I confronted him with it and he said; that because he was so tired and stressed out, he just felt more secure with having them with him, just incase ... Now, after the affair, he says that because I've found out about the viagra, he just doesn't feel comfortable with me, knowing that he might have taken viagra to have sex, that me knowing this, takes away his desire to have sex, because I might question if he really desires me or if it's the viagra talking..

I have made some harsh comments about the viagra, I felt hurt and very insecure about it, he was only willing to having sex with me once or twice a month ( when I was ovulating, as we were trying to conceive ), and he needed viagra to make that happen, it made me think he didn't find me attractive enough, I made it all about me, instead of trying to understand him better ..

So now we are not having any sex since a year, we are not looking for a house anymore, all the serious future projects are off the table, he is working more then he ever did, we are kind of ok as long as we don't talk about all the serious things, but at least twice a month ( while I'm ovulating or before my period ) I really need to talk about it and his way of dealing with it is avoiding it and when I bring it up, he says I'm not understanding his needs and issues, that he does desires to have a family, that he is not seeing that girl anymore but that he feels blocked ...

Anyone who went through something similar, any advice about what to do?
