Relationships are work. I mean, a good, healthy, stable and lasting relationship is a lot of work. You have to meet halfway. Example: When I was single I took in as many dogs as I wanted, I kept the house spotless, I was awake in the mornings and asleep by 9pm. I was high-strung and assertive, obsessive compulsive about cleanliness and making beds.
Now that I am in a relationship, not only do I need to always share, compromise and take his comfort into consideration I also cannot take in every stray dog (his limit is 2), I have to be okay with a little dirt and unkempt rooms, I have to be quiet in the morning and accept his coming home from work at midnight.
And he has to compromise too. He was independent and spontaneous. Now he has me to think about, take care of me and consider me and my schedule when making plans. He now has two dogs and an obsessively-and-compulsively clean wife. In fact, one time he woke up to go to the bathroom and come back to a made bed.
When in a relationship you have to meet halfway. Both people compromise. Both people give up comforts of their old way of life. But the best part is, both people gain a whole new person and set of comforts.
