hi I don't know if this is classed as completely cheating, but my partner just keeps lying and lying to me, we have been arguing a lot lately and he keeps telling me he wants freedom(we have been together 7years) well at the start of the relationship he lied to me about walking with this girl who I hate and then he disappears for ages and come back and tells me he was with his mates, I only found out the truth when my sister saw them and told me, he told me she just walked with him and because I was completely in love with him I let it go,

now the other night he went out with his football mates but deep down I knew he was going out with his womaniser friend who I don't trust and I did something terrible I pretended I was him and messaged his mate and I knew my suspensions  was right he went out with him so I kept talking about girls etc and his mate turnt around and told me that a girl was speaking to him, so we had this big argument and he keeps denying it over and over, but why would his friend message that if he thinks he's messaging my partner ? hmm well my anger grew because when he got back he got a shower and now after that message I think more went on and he's cheated on me,I'm stuck what to do as this man is my life I gave up everything for him
