Yes he seems to get bored and message other females. A few years ago he signed up to a cheaters dating site. I always seem catch him out. He denies there being any physical cheating apart fronwith his ex when we first started dating. We have three kids together and I thought we were going really good it’s been a year and a half without any cheating then I find out about this lady from high school he has been inappropriately messaging for a month.
Hello Grub, you deserve much better than this, once a cheater always a cheater, and no matter how much he says that he will mend his ways, you can never be sure.
You can't keep wondering what he's up to, because you can't believe him, he has broken your trust and integrity.
You have 3 kids to look after and he still has a financial obligation to abide by, but he has to leave you.
Trust must be earned, not now, not yesterday but all the time, I'm sorry but he can't do this.
Take care and please let us know how you are getting on.
