Can't stop thinking about him..

So it's been 4 days since my 11 hour plane journey home to my husband where I sat next to and talked with this guy who I cannot get off my mind. He was so interesting, sweet and attractive and its driving me crazy! I have him a fake number of course because I am married and would never be unfaithful but I kind of regret it! How terrible am I!? 🙁 I can't even get close to my husband right now (I have been feeling almost like iv fallen out of love with my husband for a few months now) and this experience just confirmed it I guess but I feel like I do still love my husband. Eughh what to do! I can't stomach the thought of even having sex with My husband right now and we haven't done so for a month! I feel awful and even worse that j wish I had got this guys number! Help me please someone I am going insane!
