Im 25 and I've had experience which did break my heart. After that I built a stronghold so I was immune to pain, but so I was immune to love. This woman I still love and she is going to be my wife. I was unable to have normal healthy relationships because of my addictions to all sorts of things which kept me out of the way. I refused dating a girl because I told her, I love you but I can't keep myself together from it. However, God instantly freed me of gaming addiction, internet addiction, p*rn addiction and masturbation addiction as well. The freedom I couldn't enjoy before came. But Even without all this, I was pretty much a guy who used to be alone in his gaming "den".
Nobody can push a relationship on you. I hated that in the past, when people told me, I know a beautiful girl from the closest village. Instant turn off - why should others tell me , when I was taught I can't even look at a girl without others saying "he's looking at her" and similar bs, which made me hate it when girls were proposing that I date them and similar stuff. It was completely strange to me and actually only those girls I didn't fall for, only they came and asked me. It was rare that I fell for some girl, but I still didn't let people see.
Still a bad marriage is worse than no marriage. You can stay alone but you'll get frustrated over time, especially if your body wants what you can't just have. And if you are unable to cope with it, you will be uncomfortable with it, you will be very likely driven slowly to madness :p. I didn't want to change but I had to and later I wanted it. You were made because Someone loved you before your parents came to know you. If you are afraid of relationships, you might be afraid of more than that. Getting to know new people and getting comportable with it is part of it.
