In your opinion can bad boys turn good.

My answer to that question is anything is possible, but it’s very unlikely.  Typically men change very little from the point where they reach their teens.  They do learn things as they progress into adulthood, however those things they learn tend to be an extension of what their character was like in their teens.  I believe women have a pre-conception of what they constitute as a man, but the reality is a woman’s pre-conception never exists in any man. Men are grown up boys and essentially what happened to them in their teens and childhood decides their character.  Whilst there character might change a bit as their life progresses, it still doesn’t change the person that they were moulded into in their teens and childhood.

I recently bumped into a guy who I really fancied about two years ago. When I first met him two years ago, we were doing an acting course together and he asked me out and I said yes. However, during a party he got really drunk and went home with another woman.

Stay well away from him!

He later apologised, I moved on, forgot about him and later met a really nice guy whose now my boyfriend.

Stay with him, unless you get to a point where you don’t like him!

But when I saw him again, I was instantly attracted to him again and the same for him to me. We exchanged numbers and on the same day he text me asked me out for lunch this weekend. I couldn't that day and have arranged to see him next weekend. I really fancy him, but won't let him play me. I'm curious to see if he has changed and maybe choose him over my boyfriend. Is this wrong?

Everyone in this world has the freedom to do what they want, so the decision is up to you in the end.  You may find it is a good decision, you may find it is a bad decision.  I would say the most likely option is it will be the bad decision.

If you are not happy with your boyfriend, then you should finish with him, then fair enough you can give this other guy a go, but I would say tread carefully.  The most likely outcome for this is that you will finish a perfectly decent boyfriend, go out with this guy for a while and then he’ll ditch you for some other option.  He didn’t like you much the first time, so I doubt things are going to change the second time round either.

If I was a woman in your situation I would tell him where to go and stay in a relationship with a nice guy if I was happy.  If I wasn’t happy with my current boyfriend then I’d still tell the guy where to go and also finish with my boyfriend and find someone else.

So I would say read my opinion there and make your own decision.
