LinkedIn profile was viewed by ex

I know this sounds ridiculous but my stomach is again I knots and I look to all you wonderful people for support...

I just went on my LinkedIn profile...I just set mine up last month...I saw that the ex viewed my profile yesterday...and the thing is he knows that you can see who views your profile...and then I told my sister about this...she said ooh yea forgot to tell you that I received an email on Sunday from linkden saying (exs name) wants to connect with you

I REFUSED TO LOOK at his profile...bc then of course he can see that I saw it....

Also he is in the medical industry ( not a doctor) and his profile pic is of him on a motorcycle.....wtf????

So either he wanted my sister or I to see his profile pic to boast he bough a motorcycle ( prob just sat his ugly ass on one in a parking lot and it's not even his) or anther gut feeling is that he has something on his profile that he wants me to see or hear about, such as indicating he's moving to where the OW is...which is 1300 miles away....not so sure about the second thing

I know I know I shouldn't give a darn tooting....it just makes me skin creep when I see his name....that's how I know that I am lifting the N fog....

Of course my sister ignored his request...I don't know what the motive is....my sister has his phone number blocked from calling her cell...

This is to creepy...this is not normal...why on earth would he think my sister would ever want anything to do with him!!!
