Did he or did he not cheat on me?

I am not sure if he cheated on me or not. Me and my husband was invited to come see his best friend and his wife in Chicago, but I had to p because I had to work so I told my husband to go without me. When he got there he called me to let me know he made it. Well his best friend and wife had planed on taking my husband to a event there, however the event was canceled because his best friend had been called in to work on his day off. His best friend was mad but he had to go so his wife told him to take my husband out so it wouldn’t be a wasted trip. So they went out. The next morning the wife got up to o to the grocery store to make them some breakfast before they woke. But as she was leaving she found a condom full of *** at her front door and she went off. Her husband said “ it’s not mine so she woke my husband and asked him who condom is this? My husband told her that it wasn’t his best friend and she said then it must be yours. When his best friend wife called to tell me I almost ped out. When I called my husband he said that his best friend cheated on his wife and forgot he had the condom on so he lied for him because she was tearing up the house. My husband got into a argument about him lying and he hung up on me and wouldn’t answer the phone anymore, but his best friend and wife called me and told me that the condom belong to my husband and that they had went to a strip club and both had lap dances in private rooms. My husband swears that they were lying on him but my husband have been so attentive lately and we have been having 7 days a week at least twice. We have at least 4 times a week but something is not right. We have been married 9 years and we have had are disagreements but he and I are partners, lovers, parents and husband and wife. He has raised my children as his own and he is very good to us but I still don’t believe he is telling me every thing and it’s tearing me up because he loves me and I don't questioned that but he has been up under me like a child that has'nt seen his mother allday and he wants me to come with him every where!
