What to do after ending a long-term relationship?

So I broke up with my boyfriend of almost 3 years about a month ago...and it didn't go well. After a few weeks of being single, I hooked up with a guy for a few weekends. He asked me out the 2nd weekend and told his army buddies we were together....I later asked to take a step back, which he agreed to, but it seemed to hurt him that I wasn't ready to be in a relationship (even tho I had been single for like 2 weeks). Then he went on leave and ghosted me after 2 weeks). About a week later I made out with a guy at a bar and the next day he comes over to 'Netflix and chill.' We have been texting back and forth for a week, but it doesn't seem to be more than just a hook-up situation...and idk how I feel about that? Basically, wtf am I doing? I haven't been single in so long, is this what I'm supposed to do? Why am I getting attached to these guys so quickly and what do I do to just embrace being single??
