Love / Just found out polish GF is married [6]

Hi everyone, i've never posted on a forum before and I'm sure i'll suffer some backlash from it.
I am a female who has been in a relationship with a polish girl for 8 months, we catch up all the time and we have the best time together, I really thought she was the one, I know it sounds cliched but I dont fall in love easily and have. I always knew she was closeted and frightened to come out to her family so I was being patient, she finally told me last week she's married and can't leave her husband as she's sponsoring him for Permanent residency. She wants me to be patient and give her 3 months and then we'll live together. My question is, is this typical behaviour to be so dishonest, to me and her husband? I made plans for valentines day 6 weeks ago, she's just told me she needs to leave early as her husband wants to see her, am I being a pathetic female who's being taken advantage of? It's never felt like I was having an affair up until this point, we spend every weekend together even though he's home, and catch up during the week as well. I always knew about him as he's the father of their child but thought they were friends not married, she apparently doesnt live there all week. Hope this makes sense. Oh she also says they havent had sex for over a year, if thats relevant!! THanks for reading
