It's great that he got the hint and made dinner the past couple of nights, that's a lovely start. It also sounds like you need to have an honest conversation about the dogs. Sometimes couples can fall into the trap of not actually talking to each other, but just snipping. If the dogs are keeping him from sleeping or creating big messes that he has to deal with, then yes he has some grievances to air. However, if he just doesn't like sharing your time then that is a different matter. There are some men who get petty, jealous and resentful of their own children because it takes their SO's attention away from them. It's best if you find out now if that's his pattern BEFORE you commit to each other in a major way.
You two are both plenty old enough to live together independantly of parents, but it's important to come to each other with love and respect when you have issues. It sounds like underneath it all, that may be the bigger problem.
