need some help ladies 😞

So let me start by saying I am 35 weeks pregnant... last weekend I found out my SO has been cheating with his ex.. needless to say I am devastated and trying to figure out what to do. Please not nasty comments I can't deal with them but I am trying to work it out for our daughter.. well I go into my ob and get tested for everything to be safe and worst fever comes with a phone call at 240 today he gave me chlamydia.. amazing right.. well my question is does anyone know of any good book to help with dealing with cheating and things like this????
