Search Results: how to feel better after a break up

Long story
Female, 24. My ex and I broke up in May 2020, and we were no contact. I met a guy that I fell for hard, online, 6 months after my break up (Nov. 2020, we spent the whole month together), he is a chef that fell out of work due to COVID and decided to buy an RV to travel and discover a new life, with a goal of moving towards the west coast. We were instant friends, and the sex... was absolutely incredible. He did things to me I don't think will ever happen again. We started dreaming together of trying to make changes in our grueling society and try to bring some positivity. I decided to drop everything and joined him in January (he left in early December to start his trip).
Well... turns out he has a drug problem. At first I thought it was recreational, and I was fine with it, but very quickly it was clear he was a fiend. After a week from hell, I ditched him and got back in contact with my ex. I could have gone back to my family, but for some reason I called my ex (turns out the same day he had called his ex because he was lonely, and he chose me over her) and we decided to go on a week vacation to his summer house to see where we were at.
I feel better with the other guy, on many different levels, but my ex offers stability and if we don't work out I can move on and build my life. The other guy is working on becoming sober and is showing me proof, and when I left him, he had a break down and confessed he was falling in love with me, well, that he loved me. I miss him but I am scared to try again. I can set myself up with a little emergency money and bail to my family if I needed, but that's a hard road. If there hadn't been a drug problem, I would still be with the other guy. He pushed my boundaries and excited new ways to live life in me that felt right. It's easy with my ex, but almost bland, and he has a dog (I hate dogs, nice to them, but hate them). Who should I be with, if either?

I have been dating my boyfriend for about 2 years now. Around the 10 month mark of the relationship, I discovered that he hid something somewhat important to me about another girl because he didn't think it was important even though we saw her everyday. Following that, there have had been other issues of dishonesty and not being a good boyfriend like backing out of a plan we made the night before even though he didn't mind the whole week we planned it.

So, as one person does after he broke the camel's back, I told him that I am most likely going to break up with him or at least really considering it because he indirectly got smart with me when I asked if our photo album came in the mail. We texted for HOURS over the phone trying to discuss it and the whole time I'm mad because I am already mentally drained from the relationship.

The real thing it comes down to is if he's either willing to change for the sake of this relationship like being able to adapt/actually be with someone, or is he just keeping me around/being selfish. Last time we spoke this intensely was earlier this month and he promised to be more honest/open, yet all he was doing was continually giving me compliments for no reason every minute of the day. When I said that was too much, he used it against me saying it made him feel bad and will have a "hard time" being "open" again. He still gives me random compliments now as well even though he has never done that prior to that conversation really.

He does know that he is selfish sometimes since he stated it himself that I deserve better, but yet still promises change. I'm not sure what to do, what do you think?
