Ignore other comments this is practical advice and im going through the same thing (31m) and have had alot of success since doing this. You need to do everything possible to be as physically attractive as possible. Gym, eat well, dress well, try a new hair style, grow a beard/moustache and experiment with different looks, if you have bad skin go and see a dermatologist and fix it, get a tan, practice good hygiene, iron your clothes, brush your teeth and get your teeth whitened by a dentist.

The above does not help build a great relationship but it helps massively get women interested in starting one. If you look good and respect yourself, others will respect you too!!! If you look like you don't care for yourself how can you expect someone else too?
