I'm in a relationship but feels lonely he keeps breaking up for the silliest and stupidest things what should I do?

Just drop him. if he can't handle even the slightest things, what more for those greater parts, right?

When you're in a relationship, the most important thing is Understanding. Understanding means getting to know more about what you want and what your partner's want. Most of the time people get into a relationship because they feel lonely, they feel like there is a missing piece in their life. Be kind to yourself first until you feel content with yourself, love yourself and you feel like marrying yourself. In this way, you'll understand what you want and what your partner's want. If you've tried to understand your partner but your partner doesn't want to understand you, try talking it out. if it doesn't work then, let go of your partner, It'll be hard to let go but it's for your own happiness.

If you are in a relationship and feels lonely, if he keeps breaking up with you for the smallest of reasons which aren't even necessary maybe its time that you think about it. Relationships are incomplete without love, and the one who loves, can never leave you. It's important to know that you matter. And for working out a relationship, there's need of will from both sides. And if you feel that you're not getting what you want or expect in your relationship, I think you should give yourself sometime and consider breaking up, as it would work for both. It will definitely be hard, but eventually you'll get over and feel better than before :)
