Firstly you really need to get over your ex. I realise it's obviously not a very easy thing to do but if you're still 'pining' for him it's going affect any other dates you might decide to go on.
Irrelevant but serious question. Is it dumb to wait on someone?
Possibly irrelevant background (I'll leave it to the interested reader to decide):
Last year when I met my ex I was interested in the idea of remaining friends. He found out that I liked Joshua Harris's books and read
I Kissed Dating Goodbye. He didn't put much stock into it. But he is a very committed Christian and there are many things to admire about him, so I wasn't upset. We dated for several months. It was pretty low-key, even after we started to call it a relationship. We were very committed to purity, and I drew strict boundaries which he always respected and observed. So I felt that our relationship was godly, and I did not feel that it had a deleterious effect on my other relationships or any other aspect of my life. Possibly rather, the reverse was true, because he stated (and subsequently demonstrated) that he wanted to help me improve in some areas of my life. (I, in turn, he told me, was a stabilizing influence to him because of my intense commitment to purity).
He talked to our campus minister as well as an older and more mature Christian friend before deciding to break up with me. He has told me he does not want to be more than friends with anyone in college, and, as he originally put it, he has no plans to get married anytime soon. Moreover, he mentioned the Boundless webzine to me (and repeated the name for emphasis), which his friend had recommended to him. When I started reading some of the columns on the topic of relationships, I immediately noticed the strong Joshua Harris-esque overtones (in fact, multiple columns even cite his books). It appears to strongly advocate friendships in lieu of dating before engagement, and the exploration of marriage is central to all romantic relationships. I was surprised (though somewhat pleasantly) at his changed perspective.
I have tried continually to respect his desire to keep it a friendship (and I have felt convicted that at the time a relationship was not right for us, and we erred in entering one.) All things considered, we remain fairly close friends. Our time together is limited and we mainly see each other at church and our Christian college group activities. But he assured me (and made me repeat) that I could talk to him about anything. He is always very polite, considerate, supportive and encouraging. In some sense, though I try to hold back, I still instinctively look to him for spiritual leadership. I appreciate his excellent and mature perspectives and value his advice. I pray for him every day.
The often confusing factor is that he still has feelings for me as well, and though he has always been consistant in calling it a friendship, sometimes he wanders slightly across the boundary line (never physically, only in when, where, and how we hang out - i.e. watching a movie in my room or something else that could be construed as dating.) In admitting that he screws up, he is implicitly acknowledging his continuing feelings for me. (And at any rate, I know it from his face and other cues. He's always worn his heart on his sleeve.)
It is difficult for me to know where to draw the line. Is it acceptable to have feelings for him though try to conceal them? Should I "get over" him? Is it inappropriate to allow myself to ever consider the possibility of dating him again, in a more serious context? Should I just shut the book and move on? I know I have a good deal of maturing in store for me within the next few years, but the things I admire and respect about him, and the values we share, are not going to change by this point in my life. We will change and grow, but the core of his character that I love now will most likely not.
I just need a mature perspective on all this. If it requires dashing my hopes, then please feel at liberty to do so. I want the best thing for both of us and what is right in the eyes of the Lord, even if it's not easy.
