I think you should talk to him
personally I think he overreacted (obviously depends on the context)
im going through the same situation as u. infact, i didnt just kissed another guy, i did something worst. thing is we weren't on a break, we broke up 2 days before that, got back together after a month, told him and he blamed me for ruining everything. im still not over him but i decided i have to be strong about this or ruin my future as i went through a really bad time after the breakup. just be strong and dont think about tha person
...You were on a break. Clearly the love you think is there isn't if you a)went through a rough patch and b) kissed another guy.
Tell him how you feel though, otherwise you'll ask yourself "what if"
My first love lasted 2 years before she cheated on me. it took ages of being dragged out and when it was over it was more of a relief than anything. Without that long stretch (about 2 months) of time having the whole structure of the relationship fall appart in front of me, it would have been so much harder to move on from. I sort of know how you feel because a recent relationship ended suddenly and unexpectedly and its really difficult. I struggled to even talk to anyone but my close friends for weeks.
I don't know, maybe it's different for guys, or maybe even just me, but what helped me get over it wasn't seeing others, it was finding something to drive me, to really push me.
You can get by, or you can take control and make life your own. It's much easier said than done, i can appreciate, but look for things which just inspire you. For me i went on a month long music hunt and read loads of philosophy. By the end of it my music collection went from about 900 to about 2300 songs. I've always loved philosophy so i got into it loads.
Thats just me, you can find your own thing, it could be sport, reading, some other subject that you've never studied for example, looking into various religions, just out of interest... whatever it is.
Basically, (i've waffled on a bit too much) find what it is that drives you and take control of it. When you're ready to see people romantically you will, but there's no obligation to. Go at your own pace.
-if you want to ask for him back, do it once and once only. dont EVER ask again.
-talk to him, but if things don't go to plan, then afterwards take as much time as you can avoiding contact, you're trying to get rid of your feelings not have to suppress them.
My own life philosophy could provide a new way of looking at the world which may help:
In everything bad there is good, in every problem there is an opportunity. It may not justify it, it may not be much consolation, but if you can find it and throw all you have into it, you will find peace and happiness in the most misery filled places.
Anyway, if anything I said here helped at all then it was worth it. I hope things turn out well for you, I mean that.
How about not kissing other guys.
JUST HOW ABOUT IT?
Yes you do get over your 1st love.
