<human>: Can you condense the text into three sentences or less?

Been with my s/o 3 years, living together for 2.5.  Generally, I can say I'm happy in our relationship, he treats me right and it isn't toxic or abusive in any way I can see, except we might be a bit co-dependent.  But we are respectful and kind to one another.

But we go through cycles.  Long (3-6 month periods) of great chemistry, happiness, barely any disagreements or arguments, and those we have are short-lived or one offs.  We have a great sex life, and feel very close.  But, it's punctuated with shorter (a week to two months) periods of arguing weekly or daily, feelings of disconnect, and some bruised feelings, and lower sexual activity and intimacy.  Usually, these periods reach a peak where one of us (usually me) gets really overwhelmed and we have to sit down and have a long talk about what we're going to do, and breaking up has been on the table at least twice.  But, we've managed to turn things around and make them better than before.

We're going through a somewhat low period, but not as intense as in the past.  Just a general feeling of frustration over minor to moderate issues.  Stuff like quality time, division and timeliness of chores, and other things.  I love him very much, and I think we work together really well, as a team and a couple.  But these feelings of low confidence in us is recurring... is that normal?  Or should I be examining whether or not I should think about leaving?  Would counselling be a help?
<bot>: S/O and I generally get on great, go through low periods of sexual activity and low palpable chemistry, usually because of tangible issues but sometimes the frustration is more subtle.  Advice?
