I have been in deep shock for 2 weeks having discovered my husband has been having an affair for 2 years!! He doesn't know that I know this. I would love some advice on how to approach this. We've been married for 12 years. The last few have been tough but i held on to us believing in him and all we were building together. I am so sad and angry. 2 kids. Any tips on what to do next would be brill. Thank you xx
