Do I really have to feel bad for cheating on my long distance relationship?
Why would you want to cheat on your partner?
The long distance is getting too much for me, I had the opportunity and I felt like doing it.
It can be hard to resist temptation, but cheating on your partner is one of the most inconsiderate things you can do. If they find out, they will be devastated and your relationship with them will likely be over. If you don't want to be with them anymore, you should end the relationship instead of cheating.
I agree. I really don't feel great about myself right now.
It's good you understand what you did was bad. What you should do from here is talk to your boyfriend and let them know what happened. Then it will be up to both of you if you want to try to fix this or if it's best if you both move on.
