Less Itself

Dear Dr.
Tracy,
I am a 33 year old divorced woman with four kids.
I was married for 12 years and I have been divorced for
approximately 3 years.
I met my new boyfriend during my divorce.
We hit it off and have been together ever
since.
He is a 44 year old divorced man.
When I met him he had been divorced for 2 years.
Well, I met his exwife and she seemed to be an okay person.
What I found out 3 months into my relationship with him was that
he was fooling around with his ex-wife again-- who also at this time had a boyfriend of her own.
I figured
that since I did not have a committed relationship with him, I had no place to say anything.
The problem is
it continued further into our relationship, up to the point when I found out I was pregnant.
At the same time I
found out that he and his ex-wife planned to go to his family reunion together.
Of course before all of this, I
drove by his house one night and saw her car parked outside his home.
The excuse I got after all of this was
that they were considering getting back together.
I thought it was very funny that as soon as she met me, she
found interest in him again.
I guess my issue is the fact that now I am still in this relationship.
I have brought a child into this nonsense
and I hate the fact that he keeps in contact with her.
My boyfriend has taken responsibility for her son from a
previous relationship.
His excuse for having so much contact with his ex-wife is because of that boy.
I know
this is not true but I have no real proof otherwise.
I have also dealt with him taking women to hotels and my
gut tells me it was her, but he promises it was not her.
I have tried to get over all the cheating.
I know that she is very close to his family and I also know that his
family does not like me because Istand up for myself.
I guess the bottom line is knowing how much contact
his ex-wife has with him and the fact that he knows I can't stand her.
Am I in a weird relationship with a man
that wants to have his cake and eat it too?
Or am I being paranoid and need to trust him when he says he
does not want her.
I have never had so much animosity towards two people in my life.
I do love this man, but
I feel like I have put myself back in an unhealthy relationship with a man that is trying to lie to me.
To be totally honest, now that I have his child I even hate the fact that he helps her son.
She never has to ask
for anything regarding that boy, but I have to constantly remind him when our son needs something.
He does it
for the other boy without thinking, but my son is a second thought even when I have said, "
Look at your son.
He is in dire need".
I was married to a cheating man and hooked up with another cheating man.
I wonder if
it's just my bad choices in men.
