Virgo's ex calls, he now needs space...help!

Hi! I met an amazing, nice Virgo man about a month ago and we connected right away... since then we spent every evening together sitting on my porch talking for hours, going for walks, etc... We kissed and hugged a lot but did not have sex. He expressed his feelings for me openly and I did the same... everything was literally euphoric and wonderful and I know it was mutual... what a lovely beginning................... fast forward to yesterday: he comes over and tells me that his ex called him to tell him that her aunt (who was more like her mother) had passed away and that for some reason she needed him there with her (she lives 6 hours away) to help her get through this horrible time. He said he told her he could not go up there at this time... she then said that if he didn't go up there she would come down here to see him after the funeral because she really needed him. He told me all of this and I was shocked and devastated. He told me that he doesn't want to lose me but he realized that there's obviously some stuff he hasn't sorted out to do with his ex and for some reason feels the need to be there for her.
I'm so hurt!!!! I agreed that he should take a bit of time to sort out all of this since her calling him after months of not hearing from her brought up a lot of conflicting feelings... but he said his feelings for me were still the same so I shouldn't worry about that... he also said he values me more than anything and wants to be fair to me and not have another woman on his mind so he needs to take some time...
For some reason I believe he's sincere... probably because of how he treated me since I met him (absolutely wonderful!!!).
I want to know what you all think about this situation. Should I let him go completely? Should call him at some point? Should I wait until he calls me? Is this 'typical' for a Virgo? What should I do—?

Your advice is cool Mr Nice. Branh is harsh ooh.
