I can always tell when this is happening to such friends, as they start to not message off their own backs, don't respond to messages sent and when they do respond, most communication is curt to say the least.
This is in itself frustrating but to have to do the maths yourself is even more irritating. Being a stupid girl, I some times think that when people don't respond to messages, it might be something to do with me (why this is my second thought, is beyond me, stupid girly brain), alas when they do eventually reply, it's short and needless of response, I instantly know there is a girl present in their life. At which point I lessen most communication and await their acknowledgement of being a shit friend. This normally happens the first time a fight happens or if they break up. If there is no such thing, I await the news that a baby/wedding is on the way and I wave goodbye to my friendship.
I know this isn't always the case, I've many male friends who have managed to keep me in their life but a lot of them seem to think you're not allowed friends or freedom, when in a relationship.
I normally don't expect to hear from my friends (female or male) for at least 3 months when they start out in a new relationship. It's only fair to expect nothing from them during the beginning. If they are totally in love with the new person in their lives, I give them another 3 months, after which I hope they'll remember us lot and get in touch. Most do and then we all carry on our merry way.
I just will never get people who think that being in a relationship, means you've no need to friends anymore. It's bollocks!
I will always need my friends. Regardless of how amazing the person who I date is. Maybe I'm backwards but I expect most of my partners to appreciate what my friends have done for me in the past and not mind when I've got to go running to them for whatever reason. Maybe this is why I'm currently single but I'd rather be this way and end up with someone who knows what I'm like from the offset, than make out that I can be 100% committed to a relationship and that my friends don't mean that much.
In other news, the new Ford KA is horrid! For some reason, they've cut and shut a Renault Megane and an old KA together - it's ugly as sin! Why they insist on taking sleak lines and making them all bulked up and steroid shaped is beyond me! Go back to design school!
