Last night it came out in an argument that my bf called bm yesterday but deleted the call from his phone...When i asked him why he deleted it he said it was to prevent an argument starting but of course it turned into an argument anyway!!

Yes I admit I have been a bit over-sensitive about issues to do with his daughter (5yrs old) lately but I cant take him going out of his way to hide things from me...its only happened once, i know there's nothing between him and his ex anymore and he said he knows he shouldn't have deleted it...should i just let this one go?
