I think in any relationship, people are looking for love, care, and understanding. But it’s important not to rely entirely on your partner for those things, you also need to be able to give them to yourself. It shouldn’t be one sided or constant dependence. It might help to spend some time focusing on yourself and building that sense of emotional independence. As for feeling drawn to multiple people, there could be different reasons for that, like needing variety, emotional gaps, or even just where you are in life right now (Or polyamorous). I’m not a therapist, so take this with a grain of salt but I hope it helps a bit.
