Just broke up with the bf

I could really use a friend right now. I literally don't have any. Going through a break up from a relationship of almost 4 years and I feel lost and sad. I lost my virginity to him and I love him but I realized that I was way better off without him because of all the lieing and talking to other girls ? I need some advice as to what I should be doing now ? How do I get over it ? How do I cope with my feelings ? ???
