I didn't read every post very carefully and just realized that you are a female. You know I was stereotyping that mostly men change oil ... lol
my advice to stay away from old people (twice your age and up) until you are at least 28-30 years old ... should now be revised to until you are 35
kidding aside, if you are for real (remember I don't trust the internet), my advice to you or your friend is:
1- still don't hang out too much with even trusted old people. Moderation is the key. there are lots of good people in your age group. You need to find more good friends close to your age to balance your views and ideas.
2- at your age, you shouldn't get too much into "closure" business. 1 or 2 or 6 months relationships should be able to handle a no closure deal/breakup within a reasonable time (i.e. less than a couple weeks or a few weeks) ...
closure is for 40 years old people and midlife crisis with very LONG relationships . Basically what I am saying is to move on and don't dwell too much on the past. You can always find the next nicer, smarter and better looking guy or partner.
3- talk to your dad, parents or other relatives if you feel sad or depressed for extended period of time.
4- don't fully trust the internet and even what I just told you. I don't think Dr. Phil posts on this site.
Pandemic is almost over and we should all get out more often.
Good luck to you and your friend(s).
It wasn't me, but a good friend, and it wasn't months, but years. I do have friends within a few years of my age, just not a lot of them, and mature people who have their **** somewhat together, are much better to hang out with, and so much more interesting.
