Interesting dilemma you have brought forth. Honestly the family/friends situation is a mute point as the damage is done regardless of your feelings on
it. As sad as it may be they are long gone and can not be changed. This leaves the choice of returning as a time traveler from the past or greatly
advancing your personal experiences within your life.
If you chose to return you would be faced with a second decision. To tell or not to tell. If you tell, assuming that time travel has not been
discovered by mankind, you would be arrested and held for questioning and or scientific research or found a "nut" and incarcerated either in a
detention center or an sanitarium of some sort. The best you could hope for is that they come to believe you and they put you with a historical center
to give your expertise on the historical past. If you choose not to tell you would have to remain "under the radar" and attempt to catch up on the
changes without drawing attention to yourself in order to avoid the above scenario if it is even possible to do depending on the changes that have
occurred. All of this is assuming that by the time you return mankind has not decimated the planet and it is even capable of sustaining life as you
know it.
If you choose to go to their planet and experience life in their neck of the woods you would be taking the chance that they are not collecting you as
a willing participant to slavery, scientific research, etc. It really comes down to how much trust you have in their portrayed "good will".
As for myself, knowing that all of what I previously knew was gone and buried(even if the mentality of man had not changed the people I knew would be
gone and technology would be vastly different, ie either extremely advanced to what I am accustomed to or non existent to the same), I would choose to
go to the "alien" planet and take my chances. I have experienced mankind and the adventurous person I am would wish to experience that life as well.
Edit to add: Welcome to the Family I look forward to your future posts.
