'I don't fancy Ian Beale just for the record'
OP, I like you, you are funny and clever and have so much to offer the right person. Don't be in a rush to find the right person, you are only 25.
This man
If he's a dead ringer for your Dad, then yes, I can see it's going to be offputting. If it's just that he's ginger, what's wrong with that? I was delighted to discover DP had the ginger - all the men I love most in the world , Dad, brother, son, are all ginger and it was like a sign to me that he was one of us.
Age - age gap relationships can work but they do have their challenges. My ex was 16 years older than me and it didn't make any real difference at first. But 10 years down the line, it did. I'm late 40s and he is now early 60s and changing. The thought of being an active 65 year old with an 81 year old in the future was difficult, let alone an active 75 year old tied down with a 91 year old. As you get older, it gets worse. That may sound shallow to some, but it is going to effect your lifestyle considerably. You can't share an active retirement together. At 25 I don't suppose you are thinking of these things, but look at 70 year olds around you and how they live. Most now are still quite 'young' and able to do all the things they want to do.
