Well everybody thanks for responding. It gives me a lot to think about and that is why i poster my question. Different opinions help me make my own opinion.
First of all let me tell i am very new to this. I am trying to find out if poly is my thing, but for this moment it kills me to stop at this point. So yes, i am new. But me being new doesn't mean i am dumb or naïve. Yes i understand this love is new and living far. Yes living in the same house, cleaning, taking care of the kids and working is different than a holliday. Yes i know it wouldn't be perfect, but never in my posts i said i wish for a life with him alone. I love him deeply, feel like i know him but see him far from perfect. I predict problems if we would be in a situation where we would live together, so i understand this relationship would have to grow if i would want to come to that point. To have a mariage-like relationship with the 2 of us we would have to build. Also that is not my dream cause i truely love my husband. For different reasons and in a different way, but it is a solid, deep love. I don't want to lose either one of them.
As asked: my husband doesn't make me feel alive or passionate like my bf. They are different personalities. My husband and i have a calm, respectful relationship. With him i find peace, i can be myself, he makes me the woman i want to be in a way that i have confidence in my abilities. We laugh a lot, he is mostly my best friend. With benefits

. I adore him and look up to him.
As for the responds about me not knowing my boyfriend. I did see my boyfriend only for one week, yes. But i met him 10 months ago the first day of a holliday for more than a week and we spend a lot of time together. After that me and the family went there for more than 3 weeks. And after that, yes i was there 8days by myself. And i don't know why i feel like i should defend myself cause never i told that i have the illusion that i can compare my love for my husband with the love for my boyfriend. Or that i should compare the two. I just have feelings for him and that i know him for only short now doesn't realy change my first question in this topic. If i would ask this question a year from now, my husband and i would still have more years together than bf and i. And my husband and i would still have a family. Why focus on how well/long i know him?
For me it has more to do with the fact that the genie is out of the bottle, as somebody said. I cannot go back to how it was, cause the genie is out.
The fact that i wrote my husband and boyfriend were telling a lie was me, writing in my emotions. I am thankfull for my husband trying. Yes poly was something that i initiated and cause he loves me so much he tried. I am very thankfull for that. Also i am thankfull i happen to fall in love with a man that wants poly cause of many different reasons. For example the fact that he doesn't want to steel my husbands happiness and most important of the children.
About raising children by myself: most important for me is that a divorce would be terrible. That is not what i want for my children. Having said that, i want to say i don't know if my husband and i could even stay together mono after this intens periode. We learned a lot about ourselves and our relationship that changes everything. At this moment i feel like i don't want to lose one of them. My goal is no divorce, but the question is how to reach that goal. Can i undo my feelings? Can i ignore that other side of me, that i recently discovered? Are the children better of in a situation where i ignore myself? I truely don't know. Maybe yes, maybe no. I want to find out in therapy.
But for the person who is talking strongly about me in the situation of raising my children by myself:
That would NEVER happen. I am intelligent enough to take care of the relationship with the father of my children. Now, in our mariage we work and take care of the children about 40-60%. (Meaning he works a little bit more and i take care of the children a little bit more). We are proud of this construction and we think it is the best gift in life to give children a good relation with both mother and father. So yes, divorce is expensive and i would have to work hard to make it work, but don't judge me before you know me. The level of education between my husband and i is equal.
Why i postes this topic is cause i realy don't know what to do. I love them both, different, but both. And losing love is why i posted this. Love of husband, love of boyfriend, but also love in our childrens life. For me finances are not the big issue here. Keep Love and reduce hurt are. For everyone involved.
