Can there be a future with me only dating this married woman and making her my life partner / long term girlfriend while she has a husband and children that she shares her life with and most of her time and priority revolves around them

although she tries to make time to talk to me throughout the day and we try to see each other once or twice a week or even multiple times a week depending on our schedules, as her husband is also in an open relationship poly dating girls separately but they also do have a happy marriage with each other & they love each other and share a bed and have sex everyday regardless of having gfs

and they do most things together but they both just have girlfriends on the side that they care about and I happen to sorta be the wife’s girlfriend if that’s what you want to call me. We do have romance & emotional connection and slowly we may fall in love with time as I’m the only woman she dates and we are committed to each other.

But I’m afraid of the future because she does have the traditional marriage and is in love with her husband. I’m not one to share a partner this is my first time because I really liked her! I’m just scared and confused because I want to be her #1 priority but I know I never will be. But what if one day I become a live in girlfriend (I don’t do anything with her husband) just with her and it makes me jealous that if I did live in her house having my own room it’s like how can that work?

I imagine some days she sleeps with me and other days with her husband and it’s like I only have her part time and seeing her with the husband may make me jealous. I kinda got myself into a tough situation because we have love for each other and feel happy when we are together. But can this actually work out long term ? Has anyone ever dated a married woman and had a successful outcome being in love and accepting to share her with the husband and children?
