Please help, My hubby cheats too much.

I have been hitched to my spouse for a long time now and we have children. I wouldn’t say all is totally awful after all we have great times and he’s a decent father to my youngsters however the issue is my spouse can’t stay dedicated to me. It all began for me a year after we got hitched, I saw he was continually BBMing single young ladies and totally into these young ladies at whatever point I discovered, I cautioned him to stop that it doesn’t help our relationship however without any result. It had gotten to a degree that he was enthralling around 6 young ladies at a go, sending them cash and disregarding my hurt feelings and neglecting me.
