I Almost Went There😳

So....this guy and I have been talking for about seven months now and I really liked him and I trusted him....almost to the point of letting him take my virginity.🙄 We were getting really close and I thought I loved him and I was so close to letting him take my virginity and this morning I found out that he has a gf and they have been together for a week.....I feel so ashamed and betrayed and I am really hurt 😔😢😭 What do I do??
