Relationships has expiration date?

What do you think... I only had 2 men in my life ... 2 relationships ..

The first one, started at my sweet 16... after 9 years, my boyfriend cheated on me (twice)

Now.. I’m “happily” married (I’m happy... and sometimes I believed he is too) (married 5 years but 10 together) and I start feeling the same thing like my previous bf..

I mean ... we have a daughter ... and we want another baby (I guess that is mutual, sometimes he said that he want it too), but, “work” is more important than us.... sex is only once PER MONTH.... suddenly he wanted to reduce his weight... I don’t know ...

We share as a family, but, I don’t feel the same... I mean , I feel disappointed...

And if I talk to him, about this, I’m being childish.... because “everything its ok”

What do you think?
