I think all three are part and parcel of a normal relationship as well, but I know how you feel as it was one of my worries in the aftermath of DH's affair and us both deciding that we wanted to try and make it work.
I asked DH's views on this early on and his answer was always that of the course the children were part of it, but that he'd realised that the largest part of wanting to make us work was that he couldn't imagine life without me.
He made a huge effort to spend time with just me, he organised babysitters so we could go out, even if it was just for a walk, he arranged childcare so we could have a weekend away about two months into everything.
He recently organised a holiday just for the two of us and asked his brother to have our 3 DCs for 5 days. We went camping for a week, something we love doing and haven't done, even with the children, since DS2 came along so it really was just the two of us with no distractions.
But it was the little things. Far more affectionate, more considerate (not that he was inconsiderate before really). He has only come to bed at a different time to me twice since the end of the affair. And then only because I went to bed at a stupidly early time as I was shattered. He emails me from work to ask how I'm doing (before the affair we had never been in contact at all during the day), and not because I expect it, but because he genuinely is interested in my day.
In short we have spent far more time together since his affair was discovered than we did previously. We make time for each other. He says he even though he has always loved me, he feels now like he's fallen in love with me all over again, but that it's even stronger than the first time.
There is hope, OP, if you BOTH really want it to work. But you have to tell him your fears and he has to work to overcome them.
I also agree with previous posters that it's very hard to make a decision early on, for both of you. DH was in shock at what he'd done and how much he'd hurt me, almost as much as I was.
We both decided early on we wanted to try and make it work. Now we both know we want it to work.
Sorry if this is a bit incoherent. DS2 (3) is having a toddler moment!
