Just a thought..........sometimes, its difficult to be friends with your ex. There are lots of reasons why its is so. first, it is because of a bad break up or unreconcilable differences, infidelity/cheating. On the other hand some can just spring back from being lovers to being just friends. I read once in a magazine that one reason why men find it hard to be friends with their exes is that they were really hurt during the break up or something in the relationship that caused the break up really hurt them. Sometimes, it is nice to be friends with an ex but sometimes it would be better that you choose not to. It really depends on you and your ex if you think its better that you'd rather avoid each other coz being friends won't work. Being friends with an ex may not work with everybody,
I personally am friends with my ex and not friends with another ex.
I choose not to because seeing him, being around him or talking to him is not healthy for us both emotionally and mentaly because even after thebreak up we stil argue about a lot of things, that's why we chose not to be involved with each other's life anymore...
And having an ex as a friend also is nice... I have an ex who I am still friends with, how it happened, it just did after time. Time healed the pain andset our boundaries. He has become one of my confidant. at least with him I get unbiased opinions and advice, because I know he knows me as a friend and as a lover.
Past is past.. what happened then cannot be put on rewind. So, enjoy the present and not dwell on the past for there is still the future to look forward to.
