I think it’s best to just be honest. If you don’t like or love your girl anymore just tell them. Yeah at first it’ll hurt, yeah she’ll feel rejected but personally I would feel more rejected if a man cheats, lies, and runs away with no explanation. I want a man to just tell me straight up they don’t like me at all, and that they don’t see a future with me at all so that I can move on with my life and not have hopes of anything with that person. So yeah if you’re trying to breakup with your girlfriend tell her everything you are feeling and why you think you should breakup. Also think long and hard about it, cause some men break up and then realize they made a mistake and want there woman back. So take some time to know what you want and make a decision. It’ll sting her at first but later she’ll be thankful for your honesty instead of stringing her along. Hope my advice helps! :)
