We live in a world where we are continuously surrounded by media in some form or the other. This is what gives us the unrealistic expectation of love and relationships. However, this naivety lasts only until your first major heartbreak. It is only after that the reality of the situation starts to hit that you tend to realize reality is far from what media portrays. It is important to have standards so as to not end up settling but we also need to be mindful and realistic on what we expect from love and relationships. I was that person once.
I've had a rough life, I don't open up to people very easily, and I have my heart heavily guarded. I don't let people in easily, because I've learned they will only walk away anyways. When it comes to relationships, I have a hard time trusting the guy. I've always felt extremely insecure, the guy who was supposed to set the example of the kind of guy I wanted to spend my life with, walked out on me when I was 12, and didn't care to love me like he should of, because of him, I've always been terrified of relationships. I've had boyfriends on and off, but they never stuck around for too long because they realized how broken I was.
We have a really good time together and I like her a lot. There are, of course, healthy and unhealthy ways to deal with your past. Others react by becoming monstrously jealous in future relationships or avoid them all together. In summary: to foster security in your relationship, direct your efforts your compliments, your love, your understanding, your consideration where they need it most. Which, ya know, is great, but if you want to make some headway with their insecurities, direct your focus where they need it most.
