long distance

hey lovelies. so my boyfriend and i are in a long distance relationship we've been together for some time, but we've only been able to see eachother once because my family took a vacation trip to where he lives. we live 700 miles away from eachother. we both still live under our parents roofs and driving to eachother isnt an option. we have been thinking of getting him a plane ticket and stay with us but his mother doesn't want him to go because if something happened he'd be so far. do any of you know any alternative ways we could see eachother this summer instead of waiting for another year to see him? or a way to help convince his mother? xx
