I’m 25years, met my boyfriend 3years ago. He lied he was single later I found out he has a relationship that was shaking. After a while he left the lady and we started dating fully, he is a nice guy and way matured than I am but I noticed he is a cheat though all men cheat but he lies under the influence of alchohol. I haven’t caught him red handed but I have seen a lot of signals. He is new to IG and sometimes I help him with some things, not the social media type. Read his IG message lately and I noticed he chatted with my friend that I know and she insulted him. I didn’t see his own message, though he didn’t know she is my friend. One time he danced with my sister at a party touching her bum but he said it’s alcohol and he apologized. This again he is apologizing, I’m confused and we planning on getting married soon.
