<human>: Can you summarize the given text in a few sentences?

So i've been with my partner for a year and a half now and things were great the first year. Then my partner started getting health problems with his back (slipped disc) and stresses added to that caused him to lose his sex drive. So we've been working hard the last 6 months to try and work on getting that back. We've started using porn as a means to get in the mood.
The problem is inside his porn folder (which has been around long before me and i have no problem with him looking at porn) is that there is a video of him and his ex which is probably about 5 years before me.

The thing is i'm not really mad, i'm more jealous. I know this is his past and he said he didn't even know it was still in there and deleted it immediately but at the same time i'm struggling to get over it (it was a short video and i saw enough to put me out of the mood). I'm just a bit broken and now need some advice to get over it or find that drive again since it just seems like things aren't really working for us there.
