is he falling out of ??

Me and my husband have been together 5 years we have 3 children and we used to be the happiest family and most in love couple (everyone said this) but for the last 4 months it's changed... He doesn't touch me, kiss me, talk to me or the kids we don't have sex anymore he is constantly lying about money (he bets money on football) then lies about it. He just sits on his phone all day playing games or playing football all watching football.. Doesn't he love me anymore? What can I do he gets angry when I talk to him about it..
