today left my husband

last week I found it that my husband of 4 years was cheating on my with my bestfreind.he said he told me because he. only loves me. she's pregnant with his baby(that's the only thing stopping me from beating her ass) . he told me she was pregnat and the baby was his last week. I slapped the shit out of him and left. then I called my thot of a friend and told her I hated her. but in our prenup it says that if he cheats on me I get the house,the dogs and the cars. anyways I could never feel comfortable in that house tho.
