It is always hard when you have a spouse who acts like a child and makes you feel like you are the only one working at the marriage. You shouldn't have to feel like that and feel lonley in a marriage, you need to sit them down and say hey, we need to talk and tell them how you are feeling and tell them what they can do to change things (without making them feel bad or putting them down), just tell them how much you love them, but you can't keep going on with the way things have been going and if they don't want to listen, ask about going to a marriage counselor together, it always helps when you have somebody else to talk to about your problems and if they don't want to do that, then maybe time apart is what you need, sometimes that can make both people see how much they love the other person and sit down and think about what it is that they have done wrong for that person to leave and maybe realize they shouldn't be like that anymore and it is time for a change. You just have to have the strength to leave and give them there space to let them know that you can't go on in this marriage living like this and feeling alone, because you shouldn't have to feel like that in a marriage. Not only should both you and your spouse love eachother, but your spouse should be your best friend to.
