Did I ruin it, can I get him back?

You need to appreciate several things here. I don't know the guy age but from your profile, I presume about 30-35 as well?

Establishing a long distance relationship require a lot of patience and committments from both sides. Many people who are serious about relationships would not even consider starting one in the first place due to the stress involved.

Neediness are sign of desperation and are just not attractive to either sex. In conventional way, the boy should always be made to do the pursuing and the girl would do the choosing ie consider if a guy is worthwhile to spend time with.

This guy is obviously interested or used to in the past in you otherwise guys normally wouldn't be bothered about long distance relationships chats. The recent sex probably didn't help as it may project you as too accessible to him and overly keen to please. Guys usually appreciate things they have to fight really hard for.

The only way you can do now is to call him and talk over it honestly. You should keep it simple ie you may appear a little strong (don't use needy) because you like him etc and would like to see him more to know him better. Ask him to give you a call if he feel the same way.

If he is a good guy/ like you very much he will turn around seking you.

Only bad people and the sexmongers would ignore you. These people are not worth mentioning about and you are better off either way.

Should he turn around for you, don't have sex with him that easily, Remeber lust does not equal to love and if you want a good relationship there must be respect for you.

Is he in this relationship with you for the same reasons you are in it with him? Maybe you like him way more than he likes you. Maybe having sex with you meant something completely different than it meant for you.

If he's not ready for a serious relationship and just wants something casual than being needy and clingy are probably the reasons that's driving him away. What you can do is deal with other things in your life first and if this guy wants to contact you again he'll come around and contact you.

It's almost sounds like he got exactly what he wanted. Maybe it wasn't about you being to needy and or clingy. Sounds like he just wanted to get some ass.

Sweet cheeks, us as women are naturally clingy, its just us being affection, he should know if you had sex with him that your going to get attatched. Because your giving a big part of your self to him and for a guy they probley don't think its such a big deal however, I'm hoping he will just try to understand where your coming from. Love, be patient with him, and keep your mind off it because it will eat you alive, lol been there. But just give him time and try to explaine, good luck hun.
