Hello fam! I'm a 29F, trying to understand all things relationships. In a classic monogamous relationship, it's bound to happen that we find other people attractive, go through lull periods, disagreements, fights, dry spells etc. How should one deal with these? Personally speaking, I've found relationships to be demanding, and once I'm invested, I hate having to go through the rollercoaster of emotions, and generally don't take to them well. I'd like the first couple of months to kinda set the tone of the relationship so don't expect these to creep up initially, but would like to understand from folks, how soon can I expect these, and how do I deal with them?

Thanks!

TL;DR - how soon to expect disagreements, getting bored, and lull periods in a classic monogamous relationship?
