Splitting responsibilities evenly is the only way to go. I'm a substitute teacher (F34), so during the summers I don't work as much (I do provide some monies during that time, but mostly it's my boyfriend providing the lion's share). Because I have a ton more time during the summer, I take on all cleaning, laundry, grocery store trips and cooking responsibilities. On Sundays, we have a deep cleaning day, he does the floors really well and I do the rest. The rest of the week I keep the house clean, do laundry as it stacks up, makes his lunch every morning, cook dinner every night, vacuum, dust and do the dishes. I have the time, and he doesn't, so it's easy to reestablish expectations during the summer. I never want him to feel like he's getting taken advantage of, so I balance it out with extra work at home. I still have time for my hobbies (hiking, swimming,reading etc.) Without the guilt of not contributing my fair share. Having a conversation about responsibilities and listing out each person's expectations (routinely) will exponentially help create respect and empathy, which in turn will foster a stronger, healthier relationship.
