I'm a bit confused. In the topic title it seems like you're asking if we regret being trans, where in the topic itself it seems like you're asking if you really are trans or not because you like being a guy but are jealous of women.
I guess I'll respond to both.
In terms of regret, it's hard to regret being trans. Because regret means that you feel disappointed over something that you did. And, well, I didn't choose to be trans. I don't necessarily like it all the time, because it plays dirty tricks with my self-esteem all too often, but it's hard to regret something that I had no control over in the first place. My options were either to live as male and live in perpetual discomfort with my own body and my social role, or face the potential ridicule and ostracization for a shot at being happy with myself. So yeah, I don't like being trans all the time. I wish I didn't have to make that decision. But there's nothing I can do about it, so I can't really regret what I never had the option over. If you mean do I regret transition, though? No. Now I can finally lay in bed at night without hating my body, I finally feel like my mind and my sex-drive are working right after 13 years of them feeling wrong, I can wear the clothes that I want, and act socially how I want. I'm never going back to being male. Hell no.
In response to your question... it's hard to tell just from the limited information that you've given. I'll give you the same thing that I give to every other person who's new to the site and questioning if they're trans or not... the official DSM defintion of gender dysphoria, as well as the criteria for diagnosis. If you fit at least two of the following criteria, and they are persistent desires which have lasted at least 6 months or more continuously, you very well could be diagnosed as trans, and it's worth talking with a psychologist to investigate your possibilities further.
"Gender dysphoria: "A marked incongruence between one's experienced/expressed gender, and assigned gender... of at least 6 months duration, and manifested by 2 or more of the following indicators:"
1. Incongruence between one's experienced/expressed gender, and one's actual primary/secondary sexual characteristics. (We call this "body dysphoria.")
2. A strong desire to be rid of one's primary/secondary sexual characteristics due to this incongruence. (Or in young adolescents a desire to prevent the development of anticipated secondary sexual characteristics.)
3. A strong desire for the primary/secondary sexual characteristics of the other gender.
4. A strong desire to be the other gender. (Or some alternative gender different from one's assigned gender.)
5. A strong desire to be treated as the other gender. (Or some alternative gender different from one's assigned gender.)
6. A strong conviction that one has the typical feelings and reactions of the other gender. (Or some alternative gender different from one's assigned gender.)"
