I can be honest and say I went from a confident, independent woman to a bit of an emotional mess
You say you wish he would just tell you he doesn't love you.
Love is an action not just a word.
Read what you wrote earlier that I've put in bold above.
Do you think that someone who loves you is capable of behaving in a way that causes that reaction in you?
That isn't love, love is healthy, kind, functional... your relationship has become toxic, dysfunctional and anxious due to his repeated behaviour chipping away at your confidence and trust.
Love isn't enough, especially when both people are saying it but only one is doing it.
You are young, kind and well meaning. A man like this will be death by a thousand paper cuts for you. He will chip away at your diminishing self confidence and make you feel you have to work harder and harder to keep him happy.
The harder you work the less he will respect you and the more he will mistreat and disrespect you. The more he does that the harder you'll work. Round and round you go.
He likes young women because they are more naive, easier to manipulate and less likely to have encountered his type before.
Men like him live on the edge of "well I haven't actually cheated" but if they had the opportunity and thought they could get away with it they absolutely would, make no mistake. You and I wouldn't even if nobody would find out because we are decent and genuinely caring. But he would.
Please don't waste any more years on an arsehole like this. He's a common garden variety wanker - he is absolutely nothing special.
Has he ever cried over you like you have over him? Has he ever suffered a hit to his self esteem due to your actions the way you have due to his? No and no.
Men like this ruin womens lives. Don't be one of them my love
