Help I’m in a love triangle

So I was dating someone for four years whom I got engaged to back in nov 2017... anyways I broke up with him February 2018 and started dating someone else, his name is marcos and he was a douche bag I dated for a little over a year. Anyways karma- he broke up with me and douched me.

Sooo 3 years ago when my ex fiancé and I broke up I started seeing someone named Aaron and we hit it off the first day and dated for like 2 mos maybe, we’ll I was 19 and he was 24 and he wasn’t ready to commit and I was so I stopped talking to him.

Now that Marcos and I have been broken up for over a month (guy I dated over a year) Aaron has decided to mssg me and come back into my life but so has my ex fiancé! 🤦🏻‍♀️ & im still kinda hurt from marcos and I breaking up... we talk but not as much and well he is just distant now. I block him but he still calls me from other #s or private- which is odd for someone who wants space and time to focus on themselves, yet he tells everyone I’m the one bothering him, which I do occasionally but only after he messages me.. so back to alex and Aaron...

So Aaron and I have been seeing eachother and he’s very loving and affectionate but he has major trust issues with me.. I really like him and I feel like he could make me very happy BUT Alex is also very caring and loving and he has dealt with so much of my shit he never had to just to make me happy... so I’m just lost and confused and I don’t want to get back with Alex if I’m just going to be unhappy in a few months for the same reason I left last time but I also don’t want to give Aaron a chance and ruin something with Alex if it could have been beautiful.. get me. Dating Aaron would be a fresh start and I’d like that! But I just don’t wwnt to break anyone’s hearts right now bc mine is still broken from marcos. I just know I need to move on. Plus if y’all want pics of the guys lol so It could be easier
