Broken hearted girl 🙊😩🤷‍♀️

My boyfriend and I broke up after 7 years of relationship ,I’m not saying is all his fault but his accusing me of always arguing ..but I wonder an argument is not an argument if both parties don’t bring up a discussion(btw that’s the reason why he left me) it’s very hard to let go it’s been nearly two months and the thought of restarting a relationship all over again is very frustrating..I feel like I can’t get over him, but somehow I feel like I have been making good progress because I feel like a have a crush on a guy who I met last year at a wedding but I don’t have the courage to get to know him and I dont want to embarrass myself, what if, he has a girlfriend?what if I’m not his type? What should I do girls?
