Do i have any rights if my wife cheats on me?

i have been with my wife 9 years , married 9 years too, we have 3 kids, because of the stresses of life we haven`t really got on well for a few months, last week she told me she didn`t love me, but then i found out why, she started to see someone behind my back and now she is shifting the blame onto me, can someone tell me if i have the same rights as a woman, the thing is , if the man cheated on his wife he would be put out, i`m kinda confused because she seems to think she has done nothing wrong, but sneaking around behind my back to find another man, she doesn`t see that as cheating.............. unfortunatly i do, anyone else think the same or am i going mad, i`m not sure of my rights as we have 3 kidsand a house in both names (rented), i want to stay in my house with my kids as i was happy doing that, but she seems to think if we go to court i will get told to leave and get told i can make arrangments to see my kids, i can honestly say i haven`t showed her much attention over the past few months, but i thought love was unconditional not a convinience, any help would be appreciated. ian
