He cheated on me and I feel lonely as IDK what

Boyfriend or 5 months cheated on me… I’m so lonely, hurt and just feel played of course. He’s somewhere w his new boo while I’m here emotionally damaged, yet numb. He left me for his ex…I could tell over the last three weeks we were getting distant. I figure because we had got in a comfortable stage because we have been dating for five months that that was normal. Come to find out he was cheating, I did accuse him of cheating because everything seems so off, and he was very irritated with me. We hadn’t slept together in a month. He would start arguments around the time for bed and said he wasn’t in the mood. THANK GOD if he was sleeping w her he kept turning my down (trying to find the positive 😅)He then became very defensive, saying how could I accuse him of something like that, when, in fact he was cheating. My friend saw him out with a girl that she knew, I went to the girls page and she posted a picture of them out that same night. When he suddenly stopped texting me around 10 PM that night and he never goes to sleep that early. I waited the next day for him to call me or text me 2 PM came around had not received a text message at all. So I texted him.. and not long after he dropped my stuff off at my door and left (he does this after arguments so I knew to look outside) he even put the valentine card and stuff in the bag 😂. I’m so sad, but I’m not. I wasted 5 months and got played. I’m so angry, but it’s like I don’t even want revenge.
