My boyfriend and I have been going out for 10 months and he just recently decided the relationship was too stressful and he wanted to end it. I thought for sure he was the one for me. We were so happy together and everything was just perfect. But he said it was too stressful. Im not sure whether I should move on or I should wait for him to realize what he left. I still love him with everything I am but if I wait, he might find a different girl and I can't watch him be with another girl. After all we shared and had together, I can't have that. I miss him and I need some advice on what I should do and how to move on for now or for good.

That's weird don't you think? You thought things were perfect, and he thinks things were stressful. That's not even close. Leave him alone, and read the stickies here.

Move on! Its really hard at 1st and you don't want to hear it from anyone but it's the truth. Personal experience... I was with a guy for 1yr and 8months. Out of nowhere he broke up with me. And after 3 yrs of not talking or seeing each other he realized he made a mistake and we are kind of back together. Everything happens for a reason. If your meant to be then you will get back. It takes time. I actually just got back with my ex but I'm very confused of how he feels. Answer mine... https://www.askmehelpdesk.com/relationships/am-annoying-him-he-really-into-me-592634.html

I'm going to have to say that I disagree with you slightly.
Things don't happen for a reason in my opinion, stuff happens in your life because you make it happen, and for this boy, he didn't feel like being with you was right, so he broke it off.
There isn't just 'one' perfect person out there for you. There a plenty of people who will love you and treat you even better than this guy did. Love is a fickle emotion and relationships always have their ups and downs, but if you feel its worth the fight then you work through it together.
I would say forget this guy and move on. Would you really want to extend this heartache you're feeling for the slight chance that he might come back to you? That's not fair on you. You need to focus on your own happiness, pick yourself up, and move on with your life. Like I said, there will be many more boys who will make you feel this way, and probably many more heartbreaks (you'll most likely break a few boys hearts too!) but eventually you will find someone who is worth your fight and is willing to fight for you too, and that's what you need to look forward to :)

Good Luck, and I hope everything works out for you.xx
