Should I move in with my bi married girlfriend and her husband?

Heyy I am a gay female and I’ve been dating my girlfriend for a few months now. She is in an open marriage, her husband supports our committed relationship and her hubby said I’m more than welcome to become a live in gf one day if I’d like.

I get along with her husband as a bestie as we do not do anything sexually together, regardless we all get along great as friends. He dates other women separately and his wife dates separately (which is my gf) she is only committed to me (Besides her husband which she loves and has a great relationship with) and I’m only committed to her!

This is my first time sharing a partner and as a single queer female I sometimes struggle with jealousy of my gf sleeping with her husband. I respect her marriage and love her hubby he’s a great man but I guess I’m afraid of moving in and being jealous when my gf does things with her hubby especially sleeping together. It’s lowkey a struggle I’m trying to accept as she loves me and loves him and we are all sharing this lovely Woman. But it makes me feel that I may only receive her time, love, and attention part time.

I assume some nights she sleeps in my bed and some with her hubby separately since we are not a throuple. How do I overcome this jealousy and accepting I cannot be her #1 priority since she has a husband and also children..if I moved in with her to be close to her?

Just don’t want to feel jealousy when I see her walking into her husbands rooms or when I’m sleeping alone thinking of how they are in bed together or little moments like that where he takes away her attention and hogs her a little more since they are a family and have kids together.
