My partner has been very vocal from day one about wanting to explore poly. I didn't really want to but I wanted him so I thought I'd try. But now we're 3 months in and I can't shake the jealousy. It hurts me so bad that he feels the need to have another partner. He tells me I'm his primary and that he loves me and wants a future with me, not her. But I still feel sick to my stomach knowing he is gonna love her too.

My point is, how do I get over this? How do I shake this insane jealousy and accept that he can love us both as much as I hate this.

Also, as his primary, what does that mean? Does that mean I come first? Does that mean I get more time? What does it mean?

Thank you for your help.

Edit: I want this to work with him, so I need advice to get over the jealousy.
