I so understand why you are so worried n upset,but dont be. You and your husband are fine.Men 'talk' different to their friends, ive heard my boyfriend and its like a total different language sometimes.Its man talk.Your husband loves you and thats what matters.You husband friend is the one with the problem not your relationship. Just ignore it,move on.You have both been through so much over the years and you are sick now.Your husband is right beside you and thats what matters. When men say things to their friends,ive heard my boyfriend say stuff....later i will say...what did you mean by that you shouldnt have said that bla bla......they dont mean what they actually say to their friends....or what i mean is....men talk is sooooooooooo different to how we say things.I think ive just confused myself here lol.
Basically....if you think about it.....who knows what tomorrow will bring? Your husband loves you. Leave that conversation you overheard.If YOU had a problem you would know...you dont...your husbands friend does.
You relax and dont worry about it,you have enough to deal with.
Hope this makes sense cause i confused myself and hope you relax about what you heard.Your husband is there with you n loves you thats all that matters.
Love n hugs
