Does this sound like the set of challenges you might be facing?
- We’ve built so much together
- My partner and I have drifted into totally separate social lives
- My partner sided with their family over me again, or didn’t back me up in front of others, and I’m left unsure whether they’ll actually put us first when it counts
- We used to have our own little language
- I assumed we wanted the same things, but lately our differences keep surfacing and I can’t tell which ones are real gaps in what we value and which are just us never having checked whether we’re actually aligned.

The 5-to-1 Positivity Ratio in Relationships - The Investment Model of Commitment: Why People Stay (and Why They Leave)
Caryl Rusbult’s Investment Model proposes that commitment is driven by three factors: satisfaction (how good the relationship feels), quality of alternatives (how appealing life outside the relationship seems), and investment size (what you’ve put into it that would be lost on leaving). All three are modifiable — and understanding which is weakest gives a precise target for strengthening commitment. The model has extensive empirical support across diverse relationship types and cultures. - Regularly share novel and enjoyable activities
Do new things together — not only comfortable or habitual ones.
