confused

my wife has always shyed away from cuckolding me, but the last six months, she has been really into getting pregnant but it hasnt happened yet. I dont think my cock is going far enough in? shes been really down and her friend has seen this and paid for a holiday away for the two of them to south america. I didnt have a problem with her having a two week break, but she gave me a box to open after she had gone and I've just opened and its got her wedding ring in it? I dont know if everything is over or she is actually going to fuck someone else?
