Torn between a former flirt and a nice guy (please read, need advice badly)?

[Krissy]

How to choose between two guys? I know this is very wrong, but currently I am dating two guys. Here's my situation; I was dating a guy named Josh (began dating Oct. 2012) everything was fine in the beginning until he started to flirt with other girls on his twitter this happened a few times. Each time I would tell him he told me he was sorry and wouldn't do it again. Then one day when I was on his Reddit i saw he was asking for relationship advice (he wanted to know if he should pursue things with his step cousin!). When i read this i immediately told him it was over. I wanted nothing to do with him anymore. A few months later, I found myself missing him and wishing we were still together. We ended up getting back together.. then in the summer (2013) i went on a week cruise and I was unable to speak to him during this time. When i came back from the cruise i found messages on my phone from him saying that he had "kissed a guy" and was "confused about his sexuality" he said he couldn't speak to me about this. I didn't contact him but i looked on his twitter and turns out he was actually dating his step cousin (who is a girl) and he was not confused about his sexuality after all. About four months went by. Me being dumb decided to send him a friend request on facebook but ended up deleting it one sec later. He saw the request before i deleted it and texted me saying "why".. from there we began talking. He said he would end his relationship to be with me, that he made a mistake and was sorry. During this time I had begun talking to a guy named Mark... me and josh are technically a thing now and i also have something with the new guy Mark. I've tried to break up with Josh but i always end up nothing going through with it. he says he has changed and even cried when i told him how much he hurt me. Has he really changed? Should i just forget Josh and be with Mark? Mark is a very sweet guy, I know he would never cheat on me. But he isn't Josh... I need advice badly, I feel terrible about this. Do I go with a guy I know i can trust but doesn't have that spark i felt with josh or do i go with josh but have some trust issues? (since being back together with josh he hasn't flirting with other guys for about 2 months)

You are a single young woman, and are free to date as many guys as you like. I said, date, not sleep around. All you are doing is seeing a couple of guys and obviously, are confused about how you feel for Josh in particular.
So Mark is making ( excuse the pun ) making his mark on you, at present.

Being as confused as you are, don't make any rash decisions, just keep talking and seeing them, until you know enough deep down,, which is the right guy for you.
You have doubts around Josh, who says he's changed, but that is something he needs to prove to you.
Until you can trust him again, and stay with Mark, and see if any sparks do develop. They may be there, but your feelings for Josh, may be holding you back from feeling them.
