No. Borderline personality is a very specific diagnosis. I find Borderline Personality Disorder to be one of the most difficult personality disorders to diagnose. A casanova is generally doing nice things to get someone elses attention and is trying to make everything about the other person - the exact opposite of what someone with BPD would do.
I think it is nice when you see a man try to woo a woman. You will find culture has a lot to do with dating expectations. You may want to get to know him a little better to find out about his motives. If the large displays of affection are a little much for you, you can ask him to tone it down a bit.
Here is some information about BPD provided on the link below.
The causes of borderline personality disorder (BPD) are unknown. Genetic, family, and social factors are thought to play roles.
Risk factors for BPD include:
Abandonment in childhood or adolescence
Disrupted family life
Poor communication in the family
Sexual abuse
This personality disorder tends to occur more often in women and among hospitalized psychiatric patients.
People with BPD are often uncertain about their identity. As a result, their interests and values may change rapidly.
People with BPD also tend to see things in terms of extremes, such as either all good or all bad. Their views of other people may change quickly. A person who is looked up to one day may be looked down on the next day. These suddenly shifting feelings often lead to intense and unstable relationships.
Other symptoms of BPD include:
Fear of being abandoned
Feelings of emptiness and boredom
Frequent displays of inappropriate anger
Impulsiveness with money, substance abuse, sexual relationships, binge eating, or shoplifting
Intolerance of being alone
Repeated crises and acts of self-injury, such as wrist cutting or overdosing
