i understand the kid issue...got a family member that got remarried and going through the same thing...he's miserable...his wife, however, doesn't care what he thinks...hopefully yours does...the only way to know is just straight up talk...let it all out...good or bad, if ya'll love each other, you should
both be able to bend and flex in order to make the relationship work...no bend, no flex, then you break...

if you don't want to break, then you will do your part to help make the relationship work and she will have to do hers...they say marriage is 50/50...it isn't...it's 100/100...you have to give it all you got...hopefully ya'll can figure it out
