In general, they're a good thing. You don't need to have one to be a parent, but they are handy to have around. Mine is particularly good at fixing things and mowing the lawn. As a true modern, tough woman I could do these things myself if I really wanted, but I don't want to, so it's good he can. He does a lot of normal husband-y things; leaves objects lying around, watches sport and wipes the kids' mouths after dinner not quite as thoroughly as I do. On the plus side, he's a very involved Dad, great with the children, is really good at fixing things and likes to cook, which is nice even if he does leave a big mess. Don't mistake my words. I am not suggesting you be in a bad relationship just to have one. That is much worse than being unhappily single. However, being in a relationship means being able to communicate and make compromises, which are honestly quite small prices to pay for someone who's worth keeping around. Life is hard enough. It helps to have someone to at least share it with, the good and the bad. Here are a few more gems to bear in mind:
1. It's okay to get annoyed with the little things. Nobody likes a noisy eater or a continuously empty toilet roll. Just don't let the little things rule the day.
2. If you feel yourself getting caught up in the little things, imagine what it would be like without that person...for more than a day, I mean.
3. They have feelings, too, but don't worry, yours will always take precedent.
4. Remind yourself how lucky you are that someone is willing to take your crazy on a daily basis.
5. Because of #4, be tolerant of that person's crazy, too.
There is no single rulebook. These are more like guidelines really.* You will come up with rules of your own, rules that apply only to you and your loved one. They may even change over time (or, in my case, overnight depending on my menstrual cycle), but as long as you remember to keep the dust from collecting on your bookshelf, you should be alright.
