BEING SINGLE/A GOOD AND BAD THING

So im male and ive just turned forty years old.Idont actually know if thats good or a bad thing. What i can say is im also single and have been for two years now.
My last girlfreind died of a perscription drugs overdose and it really screwed me up for 18months afterwards. Now im seeking to once again be in a relationship again.So being on this singles site is part of that idea.
BEING SINGLE.
Well yes it can be great knowing that your pretty much able to be free as a bird and do what you like.In my situation i have no children to care and look after.Also my parents are not around anymore either so this leaves me as a free-agent extraodinare!
BUT i dont have anybody in my life that i can share everything with both for good times or bad. The companion that says good morning to you as waking up in bed.Who kisses you goodbye as you walk out the frontdoor.Then in the evening over a meal and some wine spending your intimate moments with.Be that snuggling on the sofa together or in the bedroom making love with.
These are the really important times in life i believe.
SURELY its more rewarding and humane to be with someone that loves and protects you and you them,than not feeling love again.And also surely its better to of experienced this for a short length of time than never before or again?
WELL i have and i have lost but am now trying to find that feeling once again.

I wish everyone on this site that seeks love the very best of luck.
