hearts been ripped out

Hi,new on here so bear with me,been blissfully married for 4 yrs and i suppose the last 3-4mths my husband has been a little distant.he turned 40 on last fri:woohoo: "shock horror"(i am 48)
turns out that he no longer loves me,has absolutly no feelings left towards me,dosent know what he wants anymore ,his head is totally numb.
i put a lot of it down to his really close best mate that took his own life some 14mths ago(they were really both into cars and vechicles and he had a big bust up with my eldest daughter(to whom he had a very close relasionship,this has now ended
,
he has attached himself to a 23 yr girl that we employ at weekends,she is car mad and pretty so i see her as playing the best mate and lost step daughter role,thankfully she is not interested(this is wat she has told everyone)
he is tottaly besotted with her,has told me that he loves her,sends her emails saying wants to make babies with her and think how good we could be!!!.i do believe that nothing has gone on between them (kissing/sex)
husband moved out on sat evening (as he needs to distance himself and needs time by himself)
i might add that in his previous relasionship(not married)he got totally besotted with anouther woman(this too never came to anything sexuel)
i am absolutly beside myself with grief and hurt,we have everything,cars,money,our own business.he is willing to attend councelling together and seperate.
thanks for listening

Hi Guinea. I think this man is basicly no good. The one he should be besotted with is you. Your supposed to be his wife. How can you live your life with someone that falls in love with others so easily? I think this man will just muck you about until he meets someone that is besotted with him back and he will finish with you. You are a stepping stone. You deserve better than this. You should be number one on the runway. Not second best. C
