<human>: Summarize the given text in a few sentences.

I've been with my boyfriend for almost 4 years, and we have always spent a lot of time together. Usually in spurts of staying at my house for a few nights and his house for a few nights (which ever is most convenient). Now we have a dog together and I run him every morning before work so he will go back to sleep with him when I leave. We spend almost every night of the week together (no time really during the day except on weekends). We both know it is too much, but what is the normal/best amount of nights to spend together in a relationship?
<bot>: I spend almost every night with my boyfriend, how many nights a week is normal to spend the night in a long term relationship?
