Brian is my fiance and Thomas is my longtime ex who I feel nothing for .... Interpret for me or tell me what you think.

I had a dream that I was on some kind of farm with Brian and his family it was a house though too and people worked there and Brian worked there and I was there as well a lot. There was puppies in the barn.... Randomly this really pretty girl skinny perfect hair elegant just perfect comes along and starts working there. I don't know what she did but she was there. Brian took an interest in her and let it be known. I tried my hardest to keep them away from eachother but it didn't work because he found his own ways to see and talk to her without me knowing. Then made it seem like she was into him moreso than he was into her ...but it wasn't the case. I confronted her and confronted Brian and all hell broke loose. The whole house and garage burst into flames and it was almost hellish..... I think they had fallen in love.... But as the dream went on and the buildings were burst into flames we found ourselves on a bed and the other girl was at the end of the bed half naked and shivering ...while I spoke to Brian he had a big gash on his wrist and was bleeding and was acting slightly hysterical but was sitting with me.. The woman at the end of the bed hysterically got up to leave and Brian went after her.... I went after both of them angry as hell.... There was an older lady out in the fiery barn ...and we were all looking out the window... Brian was looking at the other girl longingly... but then the girl turned into some kind of demon and spoke some creepy whispering words to Brian and he snapped out of it and she dissapeared.... I ended up in a room with Thomas who said he caught Brian red handed but wouldn't give me details..... Location changes and we're in the house with some of Brian's family the girl is there and she's ok she's with his family.... Brian leaves and the girl starts hitting me with something i kept shutting the bathroom door to shower but it kept opening and Brian wasn't there so I left.....at the end of the dream I told Brian to go do what he wants and needs to do even tho we have a child and a baby on the way.... I gave him his ring back and left...

In my interpretation.... It's making me think maybe my mind is telling me hes not faithful and I need to run.... He's never completely cheated on me but has mentally...and whenever we have fought and separated he was always looking for someone new to flirt with and things. This dream was crazy .... I just had to share even if the meaning seems clear I want to hear opinions... Thank you !
