1. Ask her what she needs and would like more of from you. She’s going to be better equipped to talk about that than any of us!
Aside from that, my suggestions would be:
2. Golden rule. Put yourself in her shoes; if you were her, would you feel you’re seeing each other enough / talking enough / working together enough / bonding enough? As a discipline I think it would be good to explicitly ask self this question at least once a week until hitting a stride, afterwards maybe just at random and special times like before big decisions.
3. Whenever you’re together, be present, focused on what you’re doing and with whom.
4. Do some things together that she enjoys, especially something she hasn’t been able to do in a while.
5. Make time to have conversations. If they need to be about something that’s wrong or some daily life thing that needs to get done, then ok, they do. But the more those things get taken care of, the more room there is to talk as friends and have fun, which I think is an important part of feeling fulfilled and that you’re actually a top priority to the other person.
6. Encourage this kind of communication! If she’s been feeling this way for a while and thought you knew, do your best to learn to perceive how she’s been trying to express that to you, but also let her know that a direct approach is also welcome so you know clearly what to work on.
7. Pray about it and pray together about this and other things.
8. Remind yourself that all this is a lifestyle pattern, not something that ca be done for a while and the problem is fixed.
Good luck 🫂
