Cheating

Morgan
Okay so Friday night my husband and I threw a party and invited a bunch of friends and I invited I hadn't seen in 4 years we have been friends for almost 10 years , so at one point in the night no one Can find her and my husband well turns out while my husband was out in the back yard starting a fire she ran out there and gave him head after a few seconds he pushed her off and came back in side I kicked her ass out . They were both drunk which so was I and I didn't pull some shit like that . He let her un button unzip and pull his dick out that was enough time to know what she was doing and run away . I'm I wrong for being mad ? And he says it's my fault for inviting her . Idk what to do .
