I agree with Mach. My H and I went to MC on and off for several years. It was really just another way for my H to buy time and continue to avoid looking at himself and his issues. IC can be helpful however it is still no guarantee. My H eventually went to IC sporadically but never really got to the root of his real issues. He could even tell the C he loves me and wants the marriage but he could never bring himself to commit to it. Our marriage would have been better and stronger had my H been willing to do the work on himself.
I do think that going to MC did eventually help my H see that it was his issues that were keeping us apart and because of it ultimately got him to IC. In that sense it was good but it took a lot of time and money to get to that point without ever really solving the problem since my H has yet to deal with his issues.
