about 3 weeks ago a casual relationship i was having with a younger man broke up, we never really got started, it lasted around 2 and a half months,

It sounds to me like one or both of you weren't really committed. I would suspect he was the most likely candidate because you say he was younger. Younger men are more likely to drag a relationship along just for the sex and the experience of being in a relationship, it's sort of a learning curve for them. But when you say it never really started that indicated to me that he did not dedicate enough to the relationship to satisfy you.

i was pretty dissapointed, but am now ok i went on the rebound straight away and went out and slept with some random guy it was fun and i will not see him again.

Well, if you enjoyed it and he enjoyed it and had no intention of taking it further, there's no damage done really. You've both had a bit of fun and moved on.

Unexpectedley this week I have met another guy,who i actually like alot and he has made it very clear he wants to get to know me and to go on dates, which i would like to, most of my friends have told me go for it and date him but i have one friend who is really bugging me and saying i should not be wanting to date anyone, cos i have just come out of a relationship.

You have just come out of a relationship and you have been on the rebound with the another guy that you mentioned above. It sounds as though you had no intention of being with that guy, it was just some sex and fun and as long as you took sexual precautions with him and he wasn't interested in a long term relationship either there was no damage done there. The fact now, is it sounds as though, now you have met this other guy you are starting to get over the younger guy you were going out with earlier. If this guy wants to date you and you want to date him, I see absolutely no reason why you shouldn't go out with this guy. To throw away the chance of going out with a guy simply because it was too soon is just ridiculous. If it was a guy you didn't really fancy then I would say best not because you are on the rebound and you were only going out with him because there's nothing better around, but it sounds to me like you are genuninely interested in him. I think you should listen to the majority of your friends and not just one. One person can be wrong, more than one person is less likely to be wrong. Forget about your last relationship, that is over with, this is an opportunity to go out with a guy you are interested in going out with, so you should definitely give it a go and go out with him.

this friend always bugs me about relationships i do have alot of male admirers and she does not.

It maybe that she is jealous, it maybe that she is just not that experienced with relationships, either way I think her advice is bad advice on this occasion and in these circumstances.

I know i have to take it slow with this guy and get to know him because i really like him,he fancies me so much,how do i take it slow ? without him thinking i dont want him

Just tell him straight, "I've just come out of a relationship, so I want to take our relationship slowly". Don't go into detail about your last relationship unless he asks you and even then keep the detail low. Just keep it simple and tell him straight and using a brief sentence or paragraph, then have something else prepared to change the subject if he gets uncomfortable with what you are saying, something positive to get away from this negative. Don't say this at the beginning of the date or before the date, say it during the date if the subject comes up or once you have accepted his next date or at the end of the date, for example you could text him saying "I really enjoyed the date, I must point out though that I want to take things slowly because I have just come out of a relationship". That way you are indicating to him that you want to carry on the relationship but that you don't want to push things too fast. You need to make it clear to him that you are not saying that you are not interested in seeing him again, you are just saying you need to take things slowly. You want him to enjoy the date first and get a taste of what you are like before dealing him any negative stuff.

If he really does like you then he will go out of his way to be understanding and not push things, if he doesn't really like you then he will use this as an excuse for the relationship to fail. If he does use it as an excuse for the relationship failing at least then the relationship fails at a time when you haven't got attached to him.
